There's one disc conversion I've seen for the 10" drums, which I know little about except for the video, that overcomes one significant shortcoming of the others: It uses a newer style "caliper bracket" and caliper assembly.
The caliper bracket provides abutments for the pads. Those abutments transfer the braking forces from the pads into the caliper bracket. LSM and clones provide no such abutments to manage the braking forces.
Google "GMT400 Rear Disc Brake Conversion (Part 1)". It's a video by EricTheCarGuy.
I'm not saying the kit shown is suitable. I'm only saying it overcomes one obvious shortcoming of others.
