No, I'm sorry, but I do not have the time to write a dissertation on how you can fight the kludges and rules of DAZ to try to convert old technology to new. How do I know this? I was part of the original V4WM crew.

I would suggest that first and foremost, you work with a modern figure, designed to work with the current weight mapping technology and learn what weight mapping is capable of.

Then, you can decide if you want to go back and try to force new technology into old figures.
