Well, the lowest branch is already four or five feet off the ground, so it's have to be an awfully tall pot place on a really unstable slope (which would also basically block the entire path through that part of the property). But it is something to contemplate if I think the tree is in peril.
Actually, that might be necessary down the road for the black one. The Skeleton is only really at risk if the Village gets really overly proactive about keeping the areas around the poles clear. There's still probably about 30-40 years before the top of that one gets anywhere near the poles and it's far enough in that no branches could ever get anywhere near the wires until about 15-20 years after that. Actually do Japanese maples ever actually GET 40+ feet tall, cause that's probably how tall it would have to get to be under their threat radar unless they really did go "dead zone"; at which point we have much bigger problems.
In contrast the black one is sort of in peril NOW, or very soon. It's in the rock wall on the other side so it's actually breaking that wall up as it grows. and is very susceptible to damage. Actually it's ALREADY fallen over once; in the big blizzard five or so years ago. What's there now is what grew back from the stump. That growth is healthy and it's more or less grown back all it lost. But pretty soon, it's probably going to be necessary to simply cut the WHOLE tree down, stump and all in order to keep the wall and driveway for being destroyed. It'd be nice to root a branch of it elsewhere before that happened, to keep the line going. Maybe as a replacement for the now near dead crabapple (no, wait that's too close to the wall still, we'd just end up having to take it down again)
