Possibly, depending on how it works. Prof still seems to get weaker when gifting to David, so it'd have to be more like David stealing the Epic's power, rather than copying their abilities. That does seem like it could be "thematically appropriate" though, and Regalia did have that whole line about how Prof isn't as unique as he thinks.
If "stealers" exist, I wonder how many there have been, I'd imagine most people wouldn't often get the chance to use the ability.
