I believe in that. But Commodore could have plunked a cheap 68020 in their machines for backwards compatilibity (like how MSX2 had a SOC MSX1 inside, PS2 had a PS1 SOC, PS3 had a PS2 SOC, and so on) and put another "real" socketed CPU as a co-processor. Or made big-box machines with CPUs on PCI cards, for infinite expansion options. "True" multitasking, perfect for CAD, 3D rendering and non-linear video editing. It would have been very cool with an architecture where the UI could be rendered with almost hard realtime and heavy processing happened elsewhere.
This is almost exactly what the plan was, until C= went out of business:

It was going to be HP PA-RISC based and have an AGA Amiga SoC, including a 68k core.
How much of Hombre is myth-and-legend? Given how little progress with made with OCS->ECS->AGA, it seems unlikely they could even have built an Amiga SoC, nevermind designed a new 64-bit chipset.
Here's some stuff:
