I'd be happy to. Right now the contest is in judging mode and only the no.1 ranked designer can submit designs. If you can re-rank my design as 1 then I can upload a revision. Thank you.
(Also if you need to work with multiple designers, you can request an extension of the top 5 phase. This would allow the top 5 designers to all submit revisions.)
The contest is still listed as judging mode. Someone from LogoTournament would have to change it back to top 5 phase (they're usually pretty accommodating). Your other option is to swap designers in and out of 1st place as you need revisions.
