Whether a lender will reconsider a client after the MCAs are paid off is up to that lender, since each one sets its own rules. A good approach is to message that lender's rep in the deal thread, explain that the MCAs have been paid off, and ask whether they are open to a fresh look.
If they are, update the application with the payoff documentation and current documents, then submit a fresh deal so the new submission is clean and easy to tell apart from the earlier one.
