Everyone is tossing in their two cents here . . .
As a husband who is crazy for his wife, I'd generally support something she wanted to do, whether I thought it was a stupid idea or not. I'd let her know my feelings about it, why it seems like a stupid idea, but she's a grown woman and can do what she wants.
If it were me, I'd probably want as much information about it as possible about it if she were to change my mind. To that end, if I can help consolidate some of the research about it for you, let me know. I'm happy to list the knowns, unknowns, pros, cons, etc.
