Yesss I'd love to do more with the two of them! They're already bouncing off each other in a really fun way. c: Re: Blue Beetle, basically any potential crime-fighting or related crises (housefires and the like) would work, should Shep be in the vicinity! Either that, or we could wait for the next violent event.

Annnd regarding out of uniform shenanigans, I'm cool with both handwaving and playing stuff out - Jaime would be more than happy to help research (he's really quite fond of it, and would be a pretty thorough helper), though he would, of course, want to get his grubby little hands on whatever intel they bring back!
