I pick this car up at 50,000 miles. Gave it it's first transmission service filter a replace 4 out of the 12 capacity dexll with Mobil 1 atf. At 53,000 miles I sucked out four more qts from the dip stick and replaced with Mobil 1 atf. Fluid never looked that bad and now its super clean. What do you guys think about replacing 4 out of the 12 qt capacity every 10,000 and drop the pan filter change every 50,000?

Sounds good to me. It's kinda like what I have to do with my Honda.
FWIW, some of the older tech manuals showed a way where you could drill a small hole in the converter, drain it, and install a certain type of rivet (w/sealer of course). There were particular spots where it was safe to drill if done carefully. I did it a couple of times back in the '80s, in one case actually tapping the hole (the converter case was plenty thick) and installing a 1/8 tapered pipe plug. I'm not sure the job would translate to the newer versions, the 4L60 and 4L65.

What model year GM car/truck is this transmission in? Pre-'87 700R4's are notorious for not going much over 60k-70k miles before dying.
Frequent fluid replacement couldn't hurt. I have one of these beasts in my '87 IROC with 85k miles. So far, so good.
