Seems like you could dodge prereqs if national wonders were capturable, like get an Oxford without building any universities or even having education? Capture probabilities for national wonders in the XML are given as zero, although the code does bypass that dice roll for recaptured cities and gifted/traded cities. Can't see anything that checks prereqs, I guess the thinking would be you probably built it yourself if you're recapturing the city. Having said that I also can't see anything about it being the revolt that destroys buildings rather than just the city changing hands so I'm probably reading it wrong Edit: Test: A city has 10 culture. Gift it to Hatty. WB hermitage for her so she's getting 4 culture per turn there. Capture immediately, hermitage stays. After 1 turn, stays, 2 turns, stays, 3 turns, hermitage is gone because her 12 culture in the city now beats its original owner's 10. Prediction: Roosy's Moais will fall into the sea on capture.
