What if... once BTSX is live, someone issues an AGS asset on the BTSX chain?

Someone, being Invictus, a delegate, or someone else, if this is still not satisfying the "regulatory environment".
But I can't see why it would be a problem, if it wasn't a problem issuing BTSX for AGS holders to begin with.

Once the donation period is over, he could just drop it there, couldn't he?

(Assuming there is a way in BTSX to issue/transfer asset to a holder of the private key)
