Keep in mind that when this is done, it will take a very long time before the old name will no longer be used and the new one is fully accepted.
Look at what some billionaire did with the name Twitter calling it X. Still people call it Twitter and tweeting and it could well be that this is never gonna end.
I can imagine that when the name SUSE and openSUSE are look-a-likes that it causes confusion, but changing a name which has been used for so long, is widely know for delivering great distro’s seems to me a drastic measure and should be avoided. I can’t imagine there are no other ways of dealing with the issue at hand.
Think about that before you decide to start using whatever name is chosen. This will hurt the brand big time.
