I have my doubts about whether this is really a problem that is worth solving, since it's not very hard to invent alias hostnames that are unlikely to collide. You could for example prefix "service8000alias." to the aliased name. But if you want to do it, since the alias is a hostname, using underscores would be a bad idea since several decades of software know that hostnames can only be LDH. As part of IDNA we reserved all hostnames of the form LL--stuff where LL is letters. The only LL currently in use is XN, for IDN A-labels. I suppose you could use AL--stuff labels for hostnames that are supposed to be aliases. There may be software that rejects LL-- names but I expect it's a lot less than stuff that rejects underscore names.
