I think you're confusing canon and non-canon. Non-Canon is everything we've written, so of course a non-canon character is fine. Canon characters are those who've appeared in the manga like the Straw hats and Aokiji and Blackbeard and so forth. they're somewhat more of a problem.

It really depends on the character and how they appear. If you have a specific idea come talk to me or Wyv about it some time and we should be able to offer some advice (same probably goes for the other marines, but it's kinda mine and Wyv's field, so...). That's about all I can say at this point.
