While doing that for 80 companies is not feasible I doubt all 80 members are opposed. Valve and AMD could talk to video card, monitor, laptop and handheld makers to pad the membership enough.
As for the democracy question a quick skim of their bylaws suggests it’s close enough.

Don’t you just need to setup a run of HDMI devices and have 80 companies invest together as a group for manufacturing, then have each company put their own sticker on it.
