Many good suggestions here. I voted for three of them and would have voted for a couple more of them, if I could.
Platinum medal for person who has the most X on the site (crossmaps maps, terminator wins, etc.): this would be pretty cool. But note that this would be a dynamic medal: you could lose it. Although, I wouldn't mind if players could keep it forever after achieving it once.
Total Wins: Totally agree. Let's recognize these milestones
Win percentage: I would only vote for this is it was modified to a ratio measure, where people weren't punished for playing 8 player games. Also, this is another dynamic medal. See my comments about Platinum.
Unique Map: Potentially a medal for every single map? That would be crazy. I would only support this if the threshold for getting it was extremely high, so that few would ever get more than say Classic and a couple of specialty maps that they have. But if it was made sufficiently high enough, then go for it. Then the problem becomes how to design a medal for each map. I will say that it might be cool have a separate thing from medals, maybe "achievements" or "ribbons" that are smaller and located below the medals. Then you could have a bunch of these there. Maybe they'd be color coded (just like real military ribbons) and you'd have to mouse-over them to get the meaning (i.e. classic).
Endurance: Don't like this. No participation trophies here (well some might argue that's what GAs are, but let's limit this type of award)
Cards Achivement: I like it, although I think that Lack has ruled this out. I'll continue to support it every time it comes up.
Score Plateau: I like this idea, but I wouldn't have it be a bronze/silver/gold medal. I think like the rank of conqueror it should be preserved by crafting a medal showing that high rank. If you make it to major you get a medal with crossed swords.
Platinum and Diamond medal levels: From the linked text in the first post, it's real hard to tell what this means. I assume it is just supposed to be 2 more levels of medals beyond Gold. I like this idea, but I think the top one should be reserved for what is described as the "Platinum" medal, here.
Length of Activity on Site: I like this idea, but it should just be based on a set number of years (not on joining in the first 6 months of this site's existence, etc.) I would add the qualification that someone should have to be actively playing during that time. Maybe they have to have at least 1 active game going for their time to contribute toward the medal. There are other ways of doing this, but I think that would be the best.
Consecutive victories: I can't tell from the link what this is supposed to be. But if it's what it sounds like, it would award medals for winning streaks. I don't like this as it can be rigged and it favors players of 1 v 1 or team games.
