Cross would probably recognize the Madyrs, but since it was only ever in the design phase decades ago, I dunno how much he'd actually know about Alms or what it can do. I imagine he'd at least have heard about it though, and I'll include that in the post.

As for your new bio... He defeated several titans in close quarters using a Northstar? With weakness in hand-to-hand being listed? Seems a little off.
