What if Pictomancer had a "Drawing Mode", similar to Bard's "Performance Mode"?

Alright hear me out then: what if you could only draw pre-made stuff that you can collect, as if they were emotes. Would that be more reasonable?

I was thinking something similar, that maybe it could be like a feature that functions kind of like adventurer plates where you're working on a "canvas", but can only decorate it with premade assets like the backgrounds, accents, and stickers you see in plates and gpose. Drag and drop elements and arrange things how you like. And then the picture could show up during /bstance or /vpose. Overall something like the Pokeball Seals in Generation IV.
Not the ideal way I would implement a drawing feature but something to minimize abuse.
