Cartoon Band Name Woes

Recently, I made a decision to change #Skulltimate's name to #Skulltima, but now I'm having regrets (maybe largely because they've been Skulltimate for like 7 years at least but whatever). The decision was made to be more original, but even now, I'm not so sure it's any better. I'm still running into problems when I think about it.

I'm now going to list the problems (possible clashes with existing things) I ran into with each name-

Skulltimate-
- Apparently, there are some Monster High sets or something that use the phrase in their name, but they may or may not spell it slightly differently. (An example I saw was the "Skultimate Science Class")
- There seems to be some (probably obscure) online store called "Skulltimate Gear" in existence. They have a Facebook page, according to Google, but I didn't see anything else on page 1, so it's probably not an issue.

Skulltima-
- Ultima is a thing.

Honestly, I think it may be a better idea to just go back to and stick with their original name. Even though I ran into two main problems with it, I'm only actually concerned about the first one, and it seems a lot less troubling to me than "Skulltima"'s name similarity to the game/series "Ultima".

So I figured I would (try to) get some non-paranoid opinions before proceeding. Keep in mind that the reason why I'm being so careful is because I'm planning on seriously working on this, and we want to be safe (and not sued) if it actually becomes a well-known cartoon. Elaboration is also appreciated, thanks.

Never mind; everyone (on here and elsewhere) seems to agree that there is no issue. I have no idea what I was thinking with the name change, and am just going to run around again, casually changing it back to the way it should be. xD
