MacPro5,1 W6600 & WX7100 egpu?

Wondering if anyone has tried this two boot macOS Sequoia from the egpu and leave the W6600 in the system for booting to Monterey when I have to do real work? Or vice versa. Don't want to waste money on a egpu if it won't work. Currently swapping cards back and forth and it's a bit annoying. Also if it works for you what enclosure are you using? Thanks in advance for the feedback.
