Not a chance- the processing power of a raspberry pi is not capable of emulating the Xbox- its barely able to handle the N64. Not to mention i dont even know of a functioning xbox emulator plus Xbox is an x86 processor – the pi is ARM. If you’d like to replicate most of retropie on your computer I created a video on how to set it up

The one advantage to having it on the PC is you’re able to use emulators that require more processing than the pi has, like pcsx2 for the PlayStation 2 which has most of the same titles as the Xbox. Retropie is at a point where it has most of the emulators it is capable of running, so you’re stuck with what’s there- namely any console before the year 2000- or more realistically 1995… See here for what retropie has:
