is the logic voltage difference not a problem?

according to <https://hackaday.com/2023/04/05/rp2040-and-5v-logic-best-friends-this-fx9000p-confirms/|https://hackaday.com/2023/04/05/rp2040-and-5v-logic-best-friends-this-fx9000p-confirms/> for input pins on the pico pi it should work as long as IOVDD is connected

but you're right we'll need level shifter for IO out.

and it looks like this project designed some shifter board as well <https://www.google.com/amp/s/www.hackster.io/news/agustin-gimenez-bernad-s-logicanalyzer-turns-a-raspberry-pi-pico-into-a-4-24-channel-100msps-marvel-6674515a398f.amp|https://www.google.com/amp/s/www.hackster.io/news/agustin-gimenez-bernad-s-logicanalyzer-turns-a-raspberry-pi-pico-into-a-4-24-channel-100msps-marvel-6674515a398f.amp>

I also want to see if we can operate the GF chips at 3.3V
