The edos would be free of the caster's control, so Minato could use this against Orochimaru (I mentioned this in that thread a few below to reason why Minato take cares of his Edos)What do you think would happen if Minato used his contract seal on an Edo Tensei?

Assuming they still have the kunai embedded in their brains?
Nothing
The kunai in the brain changes nothing. Itachi still had a kunai in his brain wen he broke out of Kabuto's edo-tensei (KA), Kabuto was tryna retrieve the kunai and rewrite the control (in his own words). An edo still having the kunai in his head or not therefore has absolutely no effect on whether contract seal works on edo or not. Contract seal breaks the link between summoner and summon. Edo-caster summons souls from the pure world and into the the impure world, and is a jutsu derived from the summoning technique (all Kabuto's own words). Therefore contract seal >edo tensei. Full stop! Not debateable
