Might as well go all in and epoxy the ram sticks/dimm slot assembly.

Would it cause overheating?

You don't have to douse the whole thing with expoxy. The dimm assembly looks like this: https://guide-images.cdn.ifixit.com/igi/dpYyM4oeOLPPTdpF.hug...

Putting epoxy around the top and bottom edges (where the retention clips are) and the right edge (where the contacts are) should make it extremely difficult to dislodge, but not impact the thermal performance of the chips (the black rectangles).

Aren't they already soldered in place in modern laptops?

Many laptops but not all laptops.

I've noticed many lower end have one soldered and one removable. Drives me crazy because then you end up with more RAM but less performance, so have to choose which hit is worse.

nah, that applies to many mid to high range laptops as well, eg. 14" thinkpads has had 1 soldered 1 removable dimm for years now.
