Shallow Depth Bathroon Vent Fan

I recently removed my bathroom vent fan to replace with a fan / light unit and discovered two things.

1. The original unit was never properly vented and has been exhausting into the unfinished attic area for the past 35 years. The surrounding insulation is fine, but I can see that the roof plywood directly above it (about four feet) is slightly more discolored that all of the other roof wood. Not rotted though.
I'll vent it properly.

2. When they cut the hole in the drywall to install the fan, they did so directly below a PVC exhaust pipe. I only have about 5-1/4" from below the pipe to my ceiling to install a fan box assembly. I don't want to cut a new hole and do a patch job on the old one. The only replacements I have found to fit have been vents only, no lighted units.

Anyone know if they make a lighted unit that shallow, or am I just out of luck?

Thanks in advance.

Suppose you just make the current hole wider to accommodate a light?

Since it is just a PVC vent I would relocate it. Four 90 degree elbows would do the trick.
