Yes, indeed.

I did it before. :-D
It can be done on a weekend.
Likewise - the tricky part is CGFX or P96 drivers.

Starting with an ECS chipset is not bad.
AGA is actually not that different from ECS.
AGA is technically more an enhancemnt of ECS.
Agreed - two extra bitplanes, double and quad speed fetch modes and some banking registers - oh, and high-res sprites.
I did actually start poking around with extending the Minimig core's colour registers a long time ago. Didn't get that far, since I was still learning (still am!) and didn't have much time to play.
