Custom keyboard with more than 12 keys?

[blezzbeats]

I have a 3D rendered keyboard that is slanted, so preferably I'd like to have a custom image for each key since it's skewed because of the perception. Is it possible to have more than 12 keys?
Alternatively, I could squeeze in the default keyboard - if it's possible to skew the bottom of it to be wider and fit?

Christoph built this in HISE, so it's possible.

@blezzbeats glsl shaders. The keyboard was also a raytracing shader that I‘ve rendered to 2000 filmstrips with a custom logic. Wouldn‘t do it again though :)
