I'd license it to the folks making minimigs and PPC Amigas for a reasonable amount. I'd also look into porting it to X86 or making AROS that port.
I'm not a big fan of the PCI expansion on classic Amigas. Outside of the fact that PCI is largely obsolete by today's standard, I can't think of anything I'd want to add that couldn't be better done by custom hardware. A TV card might be an exception to that, but I think classic Amigas are going to be fast enough for that.
