That doesn't really make any sense in the way USB works.
However if you've got a system to load and pin firmware *on suspend* and flush it post resume then you don't actually need special 'firmware' drivers just a slightly fancier lib/firmware that refcounts and handles load on suspend/delayed flush.
(and probably a sysctl for cache tuning so that typical small firmwares get cached on bigger boxes anyway for speed)
