So I've posted about various aspects of my project, and I sort of had a direction that I was thinking I would be going with it. But then I starting having second thoughts.
I started the project by bench marking a different project that uses a 32-bit PIC32 processor and for the most part, it addresses most of my needs (CAN/SPI, 200 MHz) and it runs roughly 13 bucks from Digikey/Mouser. The only shortcoming I anticipate is that it has a 3.3V ADC and I just prefer to stay in 5V ADC land. The other thing I hear about is that PICs are user friendly and I don Tweakbox 't see Microchip going anywhere anytime soon.
Then I started looking into the Appvalley TriCore MCU that runs 200 MHz with two additional cores, it has CAN/SPI which are the bare minimum of my needs, but it has a 5V tolerant ADC. It runs for about $20 bucks at Digikey/Mouser.
Now this project could go no where, or it could go somewhere, and in a way I have always been of the mindset to future proof what I can. I already have accepted I'm in over my head as well, but I guess I'm trying to get other folks perspectives who've probably been here before.

I don't know your requirement. Do you mean you need the chip run @frequency higher than 200MHz?
If possible you could evaluate EFM32GG11.
You should ask the question in Microchip forum since you are using their PIC32.

"high-speed CAN: bit speeds up to 1 Mbit/s on CAN, 5 Mbit/s on CAN-FD"
So where do you get your 200MHz need from?
Spi?, go qspi at 50MHz.
ADC voltages are nearly irrelevant if you use a 10cent opamp.
