yeh, i like that scott. I think the word "stack" or "stacked" should be seen though.

@dkazakov pick mode make sense to me at least.

I really like this proposal. Its looks like something i'd enjoy using as an artist. I prefer how the stack is an "addon" available throughout the current engines, rather than being its own separate (visible) brush engine.

It does seems that your issue with configuration, is the same reason we don't have a "brush settings" docker in the first place, so many different engines.

How will previewing be handled for rotation and ratio? (or anything else I guess) will you have to change the value and click out of the HUD to see the result?
