How are you handling startup? The approach I had in mind was putting boot flash on the second channel with a separate CS pin from PSRAM and configuring that in OTP; any idea if that would work?

Yes, sort of. Basically a tiny loader in OTP that enables nCS1 on some pin, copies code from there to ram on nCS0, reconfigures nCS1 to point to second ram. This does break usb flashing. Use swd.
