f it would have been that easy do you think DCE would have simply replicated the P5 PPC-cards without enhanceing it even only in terms of clockspeed an RAM-interface ?
Why should they? I mean, what motivation did they have for investing more time in a product that was going to be replaced in the near future? Most of all, what kind of benefit was there to be expected?
Those cards where hillariously expensive already, no need to beef up the price by modifications.
About designing CPU cards, I actually know someone that did (no, not Escena; no I'm not going to tell), it's not like this is rocket science or black magic. The question is, does the gain you'll get justify the effort? Given the limitations of the current classic Amiga hardware, this seems to me like riding a dead horse. The only advantage I could see is compatibility with old software.
