Please reconsider this voting course of action and focus on a solution like any designer would in any other design environment with constraints and a clear goal.
That assumes Relic's goal is "make the best 1v1 map pool possible within a realistic timeframe."
At this point, I'd wager their goal is "keep the community alive until CoH 3 at as low a cost as practical."
I have no doubt your methods would be effective, but they'd require Relic to divert mapmaking resources to CoH 2 and to pay Valve more patching fees.
While I'm sure there are a lot of people at Relic who care about CoH at some point you've got to make the business case to a decision maker who doesn't. I'm not sure there's a business case for putting more money into improving the automatch pool methodology when the majority of the playerbase won't appreciate it anyway.
