There are basically three options here.
The second two are the fastest.
1) Senate could take unrelated, House passed bill. Strip out all all text, insert new deal. Pong it to the House.
That meets the Constitutional requirement of “starting in the House,” even though the revised text has nothing to do with the old bill.
2) House could take old CR…which is now in the House and has a very elite parliamentary status.
Send something back Senate. Senate alters it and sends it back.
This is the fastest method.
3) House could originate brand new bill (meeting the origination clause in Article I, Section 7 of the Constitution) and send it to Senate.
Regardless, I keep hearing they are leaning toward the House starting…unless, as one GOP leadership aide told me “our conference is in full revolt.”

Option 2 would be subject to cloture and potentially a traditional filibuster…if the Senate does anything other than table it. Any changes would be subject to debate, filibuster and cloture.
