Oh come on get a big bur and be done with it
Seriously, how the CR and VDO was recorded when you fabricated the dentures is in question. The truth is remounting on a standard hinge articulator and closing the bite down WILL NOT MATCH EXACTLY in the mouth. It will be close but absolutely not dead on. This is because of the ark of closure on the articulator rarly if ever matches dead on with the condyle.
As others have stated if the max denture has the proper smile line and the patients phonetics are accurate then I would leave it alone. If fixing this on the cheap is what the Dr is after he can take a face bow mount have you mount up the case on a semi or fully adjustable articulator. I would then reduce the pin and instead of removing teeth and resetting on a baseplate I would hog out the inside of the denture and tack it to the upper arch. After you get the pin down seal the borders and do a heat cured reline. Remount and adjust for processing errors and check lateral balance. Fast and accurate where the doc doesn't have to get the big acrylic bur out.
Another easy way if you are requested to remake the denture is to spot the bite in on a simple articulator and get the occlusion close. Send it to the Dr to do the final occlusial reduction in the mouth. Dismiss patient to see if he/she can function and is comfy at this bite. When patient is happy have them return and have the Dr take a VDO record then take reline impression, Very important to have the Dr check the VDO record after the reline imp is taken. Its very easy to open the bite with this impression. Pour/mount case and fab new denture for either try in or straight to finish. Simple easy and much easier for the GP to get a proper VDO CR than using a wax rim.
Ok good luck, let us know how you handle it, I bet on the big bur
