Oh, that's something I forgot to mention. I don't want it to be a hotshoe adapter because I use a light. I'm hoping I can still use the stock mount or at least put another mount where the old one is.
I think the problem with the stock DVX mic mount is it slightly too large to snugly hold most shotguns. My AT-4073a wiggled around way too much. I use the Rode SM3 shockmount on the hotshoe. I'd say, that to make the stock mount usable, line it with some foam. Some foam tape should work. Also, you could get one of the hotshoe extenders that allows you to use multiple items. Rycote makes a few of different sizes (the 037303 Hot Shoe Extension Bar is one of the smallest). Although, if you go with an extension bar make sure that your mic won't create a shadow when you're using the light.
you could get a hotshoe extension, then both the light and shockmount could be mounted together. B&H has them in a few different sizes, here's a link to the medium one:
