Bassnut who posts here had a 12" on a G11 and did some good stuff
so perhaps he may comment on that side

The LX200GPS OTA relies on (supposedly) PERFECT re-alignment with the fork saddles so that the Level-North system reference is re-established.....or something along those lines.

Totally wrong
The level north is done by a board bolted to the DEC axle
It uses a rolling ball sensor to detect level
When it does this, it measures at three points, hence any misalignment of the sensor is self excluded. The sensor could be 5deg off level, and the process will still work.
There is no problem deforking the OTA. If the arms are a bit tight, just spring them and the OTA will slide out.
The only problem on reassy is realigning the OTA orthogonal to the RA axis
This is simple but can be time consuming. Meade do provide jacking bolt holes, so if you preset them before removing the OTA, they will give you a good datum for later reassy.
One more thing. If you have a bad back, make sure everything is well supported ( lay scope on floor ), as it is light, but very awkward to disassemble whilst avoiding scratches.
