If anything is going to happen, it's going to have to be in the spending bill. Even if Trump really truly supports us, there is no way that he or anybody around him will want the administration to look weak and like he capitulated.

We know that Democrats are ok with giving up some border security, but they won't go for the wall, and Trump doesn't seem to want to move away from that position. Even if Congress sends him something reasonable like Flake's bill, they can't force the President to sign it. They have to force him to do it in a veto-proof spending bill.

It's omnibus or bust.
