What wawa said.
The Vampire is a CPU card with added bonus features, the Amiga chipset is still there and used.
I have no interest in something like what you describe, Nova.
I like my classic HW, just want it to perform faster.
For the record, I have a A4000/060 with RTG and a 060/PPC A1200.
From what I've seen, the Vampire (with its RTG) is faster than my A4000 and probably faster or equal to my 160Mhz PPC.
Once Vampire is available for both these platforms, I'll be very happy to replace the old accelerators.
But, that's just me
