This is something that could maybe happen once they fix the issue with the upper half of the tower floating when the lower half is destroyed. Until then, this is one of those things that will wait.

It's disappointing that you opted to downvote a good idea which you've indicated to agree with in principle just because you think some other problem is more urgent. I urge you to reconsider. In particular because the damage handling is not an artwork issue, but a code issue, while the mirroring is primarily an artwork issue.
