We can't give legal advice of that sort here, and trying to do so without reviewing full financials would be irresponsible anyway.
This much I can tell you about the law:
1. A Chapter 13 requires regular monthly income. A Plan is an essential part, and a Plan is a payoff plan. Funds make that happen.
2. For a Chapter 13 Plan to be "Approved" by the Court, it must be "feasible" and it must give the creditors more money than they would have gotten from a "hypothetical Chapter 7 case" filed by the Debtor as of the original date of filing.
3. Some situations call for what is called a "Chapter 20" (no such section of the law exists), that being a Chapter 7 filed first to get a quick discharge of the most troublesome debts, then almost immediately after that case is closed, a Chapter 13 is filed to get what it can give, like forcing modifications of leases or stripping second-mortgage liens on properties or other things...or even getting a discharge of things like a punitive damages award debt which cannot be discharged in a Chapter 7.
Chapter 13 Plans are based on a budget that must fall within allowable limits. The left-over money is what gets paid to the Trustee
and then to the creditors.
We really cannot tell what type of filing works best before looking at the financial details, AND considering the debtor's goals and priorities.
