I think Booster's going to get in on the imminent Arkham breakout, Robin's going to be Batting around the Gotham night doing his normal patrol duties, and Tim is either chatting with a teacup in Wayne Manor, or taking a former embodiment of the concept of Time out on a tour of Gotham. (His name's Lobsang. He's kinda cool. If we got mugged it would be hilarious. And if Kurt rescued us it would save Tim from having to go all kung-fu in front of a stranger. Just throwing that out as an option.)
So yes, far as I'm concerned, any one of these four things could intersect with Kurt if you were of a mind.
Personally I rather liked our idea that the Bats would notice Kurt's handiwork before they found Kurt- or he found them, as you like. I guess it depends on who you'd like him to meet, and with how many people in-scene!
