Yes, that's definitely an approach. I believe this is close to what @andreika did to support his 5v kinetis chip at viewtopic.php?f=4&t=1516

The tricore and GTM can do some cool stuff. However, I don't think it's worth our time to port rusefi to TriCore. There isn't a real problem with the stm32. The GTM is pretty cool, but we don't really need it-our existing software scheduler works just fine. Likewise, 5v I/O would be pretty neat, but we seem to be getting along just fine.

The other trouble is the cost of TriCore. The development boards, compiler, debugger, and other tooling cost an order of magnitude (or more) more than that for the stm32.

Ultimately, I think ports to new architectures are net a distraction from real improvements that are needed in the firmware that are architecture-agnostic.
