Easy answer: A 1024 x 512 pixel display in 16k colours like what for example the Q40 has is going to need a sloppy 1.5 MB of video memory - Twice of what the Trump card can provide. High colour, hi-res GD2 graphics simply won't work in the address space of a 68008.
Beyond that, the poor 68008 might run into some severe performance problems shoving that many screen bytes around.
Even if you'd go back to palletized colour (256 colours) like the Aurora, you still need 512KB, which wouldn't leave a lot for programs.
256 colors and 512x256 resolution cost you 256kBytes, and the 8-bit colour mode is even simpler (faster) to handle than the QL native colours. That could just barely work.
