Slanting floor

Here's my problem. I recently removed a wall between my living room and a "porch" area, a room about 8FT wide and the width of my home. The house was built in the 1920s and the "porch" room appears to have been added on some time after. In the full basement there is an additional cinder block foundation under the "Porch" area with a concrete floor.

The floor under the living room is 3/4 x 3 3/4 plank with approximately 1/4 " spacing over 2 x 8 joists spaced very erratically anywhere from 10" to 12". 5/16" wood parquet floor directly on top that I intend to replace as it is dried out, stained, and worn.

The floor over the "porch" is 3/4 x 2 1/4 T&G over 2x6 joists that but a center perpendicular double joist, spaced erratically between 20" and 19" plastic tile on top to be removed.

The floor over the "porch" slants to the front door approximately 1 1/2" in the first 4 feet and then levels out so that the drop over the 8' is still about 1 1/2".

The front door is not a problem, I have about 3", having anticipated correcting the level and possible ceramic tile for the entryway when the door was changed.

Im thinking of removing the T&G over the porch and leveling the joists with 2 x 4 cut to size and glued screwed to existing joists. Then top with plywood. would get a match to the living room but Im thinking 1 with plywood over living room, or does it need to be thinker? Or would it be better to match floors and put down another surface over entire room?

Havent decided on actual floor yet, wood or laminate with tile by entryway.

Thanks for whatever advice!

Slanting floor

It is interesting that the porch floor slants toward the door. Most porch floors slant away from the door for run-off of rain. I once lived in a house where I had the back porch enclosed and turned into a downstairs full bath and mud room. The contractor furred the floor by stripping 2x4s to make the floor level. When complete, one would have never known that the new room was a porch. It looked like a room addition.
