If you're okay with supporting her and aren't likely to feel resentment (and she's okay with whatever arrangement of things you two work out), then it can work.
ESPECIALLY if you have several interests in common that aren't contingent on education level (rock climbing, etc). Because you will be seeing someone across a class divide there, and you want to make sure there are things you can easily do together where she won't feel pressured for not having more education/stupid.
