IIRC, what Reid did to move the current Senate bill is to take an unimportant House bill that wasn’t going to be passed, and he edited out almost all the text and substituted all of the text for the current Senate bill. That’s also how they were able to have a floor vote on it without going through committee. (The 3 bills that they used to build the final Senate bill all went through committee, though.)
Therefore, it is already set up to be a reconciliation bill with regard to procedural matters. They still have to make some major edits, and under the Byrd Rule it cannot have any provisions longer than 10 years.
But I could be wrong.
