I haven't read those comics, but him mentioning his forefather's doesn't preclude him from being revived. I am not well versed enough to argue the technical issue, personally I can not find any solid facts saying his given name was in fact Mandalore or it was just his title.
I am merely expressing from a narrative point of view, I like that option a hell of a lot better than the idea that the some illustrious leader has nothing better to do than hang around a bunch of Jedi, shouldn't he be off restoring an empire?
On a side note Darth Nuke you mention that there is already another and that HK encountered this new "Mandalore" from a timing point of view I can't see why it would not be the same Mandalore that Revan defeated. There is no definitive sense of timing handed out - we don't know exactly how long HK was lost to Revan, when HK was constructed or exactly how far along Revan was by the time he ended the Mandalore wars with Mandalore's defeat. I had always assumed that Revan was well down his dark path by then, and had already constructed HK sent him of into Mandalorian space and lost contact with him.
