Depends what "realistic" means. 2 years? 5 years? If you want it within 1-year then it depends who is paying for the development. Realistically probably not not.

Which FPGA? We had this discussion. The bigger & faster the FPGA the more expensive it would be. You really have to choose a price and then try and fit a core to that FPGA but seeing as how no core exists right now, no-one knows.

How many pins do you have on the FPGA? Maximum would probably be the entire high memory area (anything over 16Mbytes and less than 4GBytes) but I do not know what the AmigaOS limitations are.

I don't think so, not at an acceptable price. But no-one knows what FPGA resources you need so which FPGA to use hence no-one knows the price.

Not for me (and the vast majority?) I mean on an Amiga, anything over 128Mbytes is really just showing off The Amiga programs I've used do not benefit from much over 32Mbytes. Ok so you may find one or two but not many. Certainly non the average Amiga user will want to use.

Depends how much flexibility is done with the PCB (more flexibility = higher price). As for replacing the FPGA. Probably not.
