IMO a Gallo-Germanic alliance would work if you have Goths and Alans among others move west into Frank and Alamanni territory and displacing them; there you might have the French ally with some tribes if in exchange they promise rights of settlement in the Roman remnant and parts of Gaul. Sure, a very fragile alliance, but one nonetheless.
