Victoria Rules
If there's a connection between the campaigns such that there's a plausible in-fiction explanation* for how-why this character jumped from one campaign to another, then sure - I love it. (though it really helps if the campaigns are using roughly the same rule-set; I'd have a hard time explaining how a 5e character could hope to function in my 1e-adjacent campaign, for example)A discussion in another thread made me reflect on a practice that I think has all but vanished from modern TTRPGS: the character who is considered separate from the campaign.
Back in the day (late 70s/early 80s), it was common practice to have one or two primary characters that you took with you to play in different games run by different DMs. Mine was a ranger. If you levelled up or got a new magic item, that counted going forward, even if your next game was with a different group of players, in a different setting. This was a widely accepted practice, and Gary Gygax sometimes discussed D&D as all of it was all one big campaign, with different iterations.
It strikes me that TTRPGS have radically changed in this regard. Now, it is typical for a character to be confined to one campaign, where their narrative arc plays out. Does anyone still have characters that they take with them to different campaigns? Do any games still assume this practice?
That said, back in the day it wasn't unknown for certain players' characters to mysteriously "acquire" powerful items and-or significant stat increases between leaving one campaign and appearing in another, particularly if-when the two DMs were strangers to each other. So there's that to watch out for.
* - which can include something as simple as a malfunctioning planar-travel device or spell, it doesn't have to be complicated.
