Is it possible to create a brush that has a drop shadow/multiply shadow with each stroke?

I was just wondering if it was possible to create a brush that had a drop shadow on each stroke, or a colour burn to differentiate one stroke from the next.

I love painting birds but sometimes I feel like there’s a more efficient way to paint feathers. I’ve tried with a circle that has a drop shadow as a brush tip but it only works with colour image brush tip mode.

If it is anything like this, it should be possible

Thanks for the responses guys, it appears not to be possible using the current engines. I think the solutions provided were good enough to move forward with though! The animated brush especially is very interesting for other applications
