What plan would that be?  So far, he has some talking points that are mutually exclusive.  Repeal O-care, cheaper for all and better coverage for all.  Cheaper with better coverage are pretty much mutually exclusive, no amount of buying across state lines, or tort reform is going to fix that.

As for both sides, until McConnell actually allows the Ds to participate, it will be an exclusively 1 sided process, the Rs will own whatever POS gets passed.  Trump will sign anything they put in front of him, so the Rs either need to get on the same page, or be willing to actually work with the Ds.  Since the Rs, so far aren't even willing to work with some members of their own party, I don't see it happening.
