Yeah, I think that would be interesting if it ever came up! And not completely negative since the first FMA anime was a little weird about homunculi. Probably more interesting if he got to know her first, though :|a

As for ideas - a random encounter in the library or something one day, maybe? That's where he's most likely to be sitting still. Or... during the mission / plot stuff that went up in the time it took for me to get around to replying to this? OTL It is something they're both guaranteed to be on...
