Yeah, it's a possibility but, it's not much different from an architecture standpoint from the ADL version other than the extra E cores. My next potential upgrade will be ARL switching more than just a stop gap size leap in tech like 10/11th gen were.
LC was all the rage when ADL was pre-launch with everyone saying it was almost mandatory and then I slapped a $50 cooler on it and it's perfectly fine. It depends on how much $$$$ you want to throw at things though I suppose. There's been plenty of mention of under volting things and tweaking things to bend it to their will though that seem to mitigate some of the cooling issues.
If heat were an issue I would probably skip the LC and just delid it for direct die contact instead. There was mention of the new AMD chips running hot and delidding dropped it by 20C w/o anything else out of the ordinary. Also makes a difference if you're not cramming it into a mini-ITX w/o air volume to actively and passively cool the guts of the system.
The other issue that comes with systems is dealing with the GPU heat. I think a lot of people forget that that's like putting in a space heater in addition to the CPU. If you don't have enough pressure from the case fans to force the air out it just turns into a heat soak. If you have the patience then doing Lc on both would be ideal since you're attaching both furnaces instead of just the CPU.
