No, AFAIK the only Quake engine on Amiga that can handle extended maps is the experimental one included with Qbreed. It always crashed for me though.
There are lots of large and impressive maps that don't require extended limits though, speed is going to be much more of a problem. Check these out for starters:
Marcher Fortress (could really do with extended audio, but works with a few sky graphics glitches and sound drop off)
Bastion Of The UnderWorld
Castle Of The Dark Ages
Day Of The Lords
