The thing is, increasing the resolution or the colour depth exponentially increases the amount of work that the system has to do.

>16 colours lores or increasing resolution to hires makes the graphics hardware use more DMA cycles, which are then not available to the blitter or CPU. Of course, the blitter has to do more work as well, copying more bitplanes.

At least on the Amiga you can get 32 colours with 4 bitplanes + sprites, and of course copper palette changes add even more.

I think a better option would be trying for things like full 320x256, or 50 FPS, or more sound channels with blitter mixing or something like that.
