A new Amiga portable console with new custom chipset.

With 20k you wouldn't even be able to design one custom chip.

He wouldn't need to go ASIC. Use an FPGA, and none of it is impossible. Basically a console shaped Minimig board with a PowerPC upgrade slot from the sounds of things. FPGA-Arcade may already satisfy the majority of all that. For a livingroom console, for a handheld console then he'd have to do a new board, and it might not fit a PPC addon.

Amiga console with new custom chipset that provide equal quality graphics as say of PS 2/PS 1

Well, on the graphics front the possibilities I'm finding start with OpenGraphics, OpenShader, GPGPU and potentially Number9 Graphics cores.

OpenGraphics seems to have been in the freezer for quite a while. The team lead there claims to have been distracted and helping to work on GPGPU.

The Number9 core has quite a ways to go to meet its kickstarter goal to make the core open-sourced. Interesting though.

Any would take up quite a bit of space in an FPGA implementation,

I understand that the Manticore is essentially long gone.

I haven't found anything else mentioning 3d support, but a variety of 2d VGA controllers out there.
