Darki,
like it or not, "ask your troupe" is the general answer you get for non-trivial spell proposals. It's built into ArM5 spell design. And it is part of the reason, why Ars Magica magic is far more flexible than that of other RPGs, without Mythic Europe becoming arbitrary. I gave it to you already here: https://forum.atlas-games.com/t/the-break-room/102/1 .
If you wish to go even a bit beyond that general answer, please remember Card & Board Games ARCHIVE & LINKS , and be complete, precise, stringent and literal: no 'inferences' and 'analogies' only you can see, just the ArM5 spell guidelines and ArM5 p.114f Requisites. And before arguing, please spell out completely what your argument shall show.
Cheers
