That will make the floor way too tall. Do like the others said, and
strip the floor to the plywood, and build back.

the OP didn't say what the subfloor is, or how thick it is.



If house was built mid 50s until 1990ish, I'd bet a six-pack it is
particle board underlayment over plywood or diagonal 1x4 subfloor. The
old underlayment needs to come up for a top-quality job. Exposing
subfloor also allows you to screw the hell out of it, which stiffens
floor and cuts down squeaks.
