Spelling debates/Adviser or advisor?

From Tardis Wiki, the free Doctor Who reference

Our article for the role of scientific adviser currently sits at scientific advisor. What I understand from multiple online sources is that while both are technically correct in British English, "adviser" is greatly preferred in British English, and "advisor" is preferred in American.

While I'm currently undecided on whether this should be added to SpellBot and enforced, leaning towards a yes, I am certain that any in-universe article including the word should be renamed.

Scientific advisor should be scientific adviser, as the "more British" spelling. At least The Scales of Injustice and Who Killed Kennedy use this spelling. There's a short story which is called Scientific Adviser. One short story, Second Chances, spells it "scientific advisor", so there is some in-universe precedent for the current spelling.

What we also need to consider, though, is science advisor. I'm not certain where we got that spelling from, and though I'm sure it's used in Miracle Day credits, that is an American production.
