You can. That's what traditional modchips do, and there's the Rhea/Phoebe which completely emulates that drive via that interface.
Of course, if you sit at that point in the system you have a different set of problems and capabilities. Much easier to build hardware for, but no data output, and of course you need to disassemble the console to get there in the first place.
