I am not aware of any way in RAW to add either Finesse or Quickness to a spell or device.
Finesse was discussed in Building Finesse into spells/devices earlier. You could also make the thing big enough that it cannot miss but that's it.
As for Quickness, it will happen when it happens and that's it. Yes, any Fast Casting defenses will exceed 0 Quickness. But remember that you must first determine the Form by rolling Awareness against EF 18 as your device uses neither words nor gestures, hermetic or not. This is detailed for Performance Magic in both TMRE p30 or HoH:S p58.
