I was going to ask what's holding up the ductwork, and wiring?
I'm not sure that you should remove all that before, you have something in place to take the weight.
Maybe put in some metal strapping to hold it up first.
If you have the space, then after you seal everything, you could drop some hangars and put in a grid ceiling, which would give decent access to all the mechanical bits. Depends on how much clearance you have under the ducts.
Otherwise, you could go around it with metal stud and track. It tends to be a lot faster than wood. Pretty much all you need are a pair of aviation snips, and some screws.
I'll trade you issues, my PO did the plumbing on the cheap.
