Camellia in OpenPGP is now a published part of the spec, complete with
symmetric algorithm number assignments from the IANA:

And the best way to do get started on the path to standardization is to
provide a patch for an existing implementation (probably using an
algorithm number from the experimental range [0] that implements it, to
demonstrate feasibility.

Using RFC 5581 as a template for the proposed draft would probably be
the quickest path to getting it documented and agreed upon in an
acceptable way.
