Gyah, now there's some temptation right there. What's stopping me is that I'd have to sit down and watch MKR - both series. 
Fun thought: With Kaylee being there, she'd have Ben eating out of the palm of her hand, much to Simon's annoyance, as he demands to know EVERYTHING about starships that she knows - nevermind that they don't have FTL, that's secondary to the matter. Ben wants to build his own ship someday, and he's pretty sure he can practically do it with practically nothing but spit and bailing wire if Kaylee teaches him.
Teletha would probably be in on that.
And if Geordi shows up...
Geordi: "You can't do that!"
Kaylee: "Hold my beer, I got this..."
Followed later on with...
Kaylee: "Wait, WHAT? You can DO THAT?!"
Geordi: *Legitimately puzzled* "Why not?"
