I may or may not have just pronounced that in my head as "weem and wigor"
Honestly, any Gifted Hedgie can probably get in on the whole court wizard thing if they have some tact (and probably Craft Magic, which is just a ball of yes for any tradition that can't naturally craft). Just send a (preferably eloquent) letter and a magical item as a gift; remember that the Gift's effects only work in person, and with you not even being there when the noble uses the magic item (or has his assistant test it to make sure it isn't cursed or something, but you get the idea) he won't have any reason to expect something like slight of hand. This works best for Hedgies like Elementalists, whose items have flashy and actively functioning effects like spewing gouts of fire, instantly curing illnesses, or leading their bearer to a material like water or silver; there won't be any doubt that your item is special. Of course, that won't instantly guarantee your position, since you could've gotten a magic item from elsewhere, but it will make the noble in question interested in meeting you, and while he likely won't trust you in person due to your Gift, he can watch you (in most traditions, though in most cases it'll be Craft Magic) turn a normal stick into a Charged Item, and he won't really be able to deny that ability of yours. Heck, if I were a noble and thought I was being tricked by somebody without their own magic, I'd still humor the person in question due to their apparent ability to present me with enchanted (or possibly extremely useful non-magic items, but meh) items after a bit of time, so even if they're stealing them or something they're still a highly useful resource.
That's how I see it, at any rate. It's an option with some difficulties, but it seems like it'd work, as long as your messenger doesn't steal the first enchanted item or something.
As for pros and cons...
Pros, wizard's side: Provided you prove your worth, you can probably get some expensive books and a lot of free time to advance yourself, since crafting charged items only takes hours at the very most. If you or your noble desire a truly enchanted item, you'll probably be able to get free soldiers to go with you to find vis. Elementalists with Craft Magic have a slight edge here, as any vis found can be turned into an elemental vis in exchange for losing some of it. Working for a noble is also prestigious, and you'll likely have quite a bit of defense surrounding you as long as you remain useful. With some luck, you can also deadlock the Order of Hermes in confusion, as they struggle to find a compromise between not interfering with mundanes and giving you the Join or Die... And as long as you don't go and steal the secrets of the Parma Magica, the usual result will be them leaving you alone.
Pros, noble's side: Magic! And hopefully magic items, specifically. Plus, a (generally) powerful defender against things that wish to bring you harm; wizards make great bodyguards. Plus, many of them can even extend your lifespan!
Cons, wizard's side: If you're Gifted, people won't like you; if you're UnGifted, you may struggle to remain useful for a lengthy period of time. It can be dangerous, and while you have some protection as mentioned above, this puts the attention of the Order of Hermes right on you. Most noble manors do not exist in and generally aren't even anywhere near a place with a Magic Aura, so you'll be unable to draw greater power from that source. Also, while the noble in question may sponsor excavations and the like to help you gain greater magical knowledge, you'll likely have very few resources by which to read about (Realm) Lores and your own magical tradition's abilities. The Augustan Brotherhood is an obvious exception to this Con.
Cons, noble's side: Having a court wizard will likely make you some rivals amongst fellow nobles. They're pretty expensive to pay for their books, excavations for vis or relics/texts of their traditions, and likely luxurious living standards full-time. Will likely have the Order of Hermes asking you to "give" them your wizard, and if you refuse you'll make a necessarily subtle but powerful enemy. Wizards can be unpredictable. And that Gift thing makes you look worse for having them around.
That's about how I see it. Really, this deal is best for the noble, but I think both sides have legitimate reasons to want to be and to not want to be in such an arrangement.
