You couldn't possibly still be coming to Taiwan recently?
You couldn't possibly do come to Taiwan if you possibly can.
Couldn't you possibly come to TW recently ?

Perhaps it would be better if you don't come back Taiwan in the near future.
=Perhaps you've had enough to come back Taiwan in the near future !
The single-word adverb maybe is an adverb as sentence adverb.
You may be right.
