I use inert gas all the time for this purpose, but mainly nitrogen because
it's cheaper. Since you really need to sweep _all_ of the air out of the
headspace, argon's density doesn't really buy you anything.

I'd recommend that you find a way to seal the keg with less pressure. Inert
gases do dissolve in the wine somewhat, and they affect the flavor a bit
until they come out of solution.
