Imagine this then, there are people that make new acceleratorcards (like Oli, nice fellow) so why would it be so hard to make new customchips, maybe not exactly the same in shape but ones that fit into the sockets and maybe are slightly faster. I mean, if you install an acceleratorcard then everything is going faster but the motherboard is still going in 27MHz (or whatever it is) so why not making faster customchips?
An FPGA could easily be programmed to emulate the Original custom chip tech, but as PHutch pointed out, electrically it would be unlikely to work in a real Amiga. If you make the chips faster then they won't work, the whole system needs to be designed around specific specs. Also, to interface modern chips (with modern Voltage and current requirements, not to mention skew and other weird timing issues) with decade old technology would be very expensive.
It's time to forget the old systems and move on :-(
