So, I've tried looking around a bit, and I haven't been able to find (and maybe that is due to my own incompetence or such) anything relating to this, so here we go:

I like to run my equipment as cold as I possibly can. As an electronics technician/budding electrical engineer, I have seem full well what heat can do to equipment,
and so I universally try after getting equipment to A) See what I can do to get more performance and B) Minimize and eliminate heat.

Well, with my newly purchased of a very lightly used G751JL, I couldn't help but notice that another version of the G751, with the 970m and 980m has a much larger
rear vent for heat removal.

My question is..
A) is it possible to just remove the old bottom and cooler, and slap on the cooler/bottom/fan from the upgraded version (if there is a difference in these parts)
B) If it is, are those the only three concerns that would be involved.

While I am certainly capable of opening up this laptop and discovering the answers myself without damaging anything.. I've learned it's always best to start with prior
experience and knowledge, before doing something different, lol. Thanks for everyones time and consideration!

1) not to my knowledge
2) N/A

Track down a copy of the technical repair manuals that asus use to get a good idea of the inside. I suspect this will also change your direction as it seems really not possible to me at least without butchering the device and possibly compromising longevity and performance which was the premise of the upgrade.

Hey SoCalGSXR, was wondering if you had any headway on this? I was looking into the same thing, just swapping out the bottom cover pretty much for a little more air flow more than anything. I have found some really nice used ones less than $40 that come with the rubber feet and screws. I also have a G751-JL that is severely overheating, to the point that I had to underclock due to throttling and overheating. I did mod the bottom case below the fans to allow more air, but looks terrible and looking for a better solution.

Let me know if you found anything out, as I am currently searching as well. I am actually to the point where I'm just gonna purchase the case lower section and modify it if I have to. Only thing I might see is possible extensions to elevate the board a little if needed, but didn't see much physical differences otherwise.

I believe the lower case I'm looking at is the JY, where it has the red vents instead of black, and they appear to be about half an inch taller, which might allow more air into the case, even though would be warm air, would still be better than no air, lolz.
