Is there anyway to draw/paint with a mesh as a swatch?

Attached image. I would like to use a mesh like a paint brush swatch to draw shapes, either stretch them out or dab several. Has anyone come across this in an addon or technique? Ideally it would be similar to drawing with grease pencil. I tried to figure it out with sculpt tool but you need a mesh to pull from.

This is mostly for rapid prototyping forms with fast to change colors like a painting app or the popular VR creative tools for desktop

if you have an idea of what code I could start from to read though for drawing mode I could try to build an addon
