Thanks for your suggestions, the knife round sounds like a great idea, but it does conflict with certain maps (in some maps you can't actually go over to the other side where the opposing player is located) but other than that it would make for some great fun.

Pointshop could be a potentially strong addition to the server as it would encourage players to get these "points" or "credits" to purchase their item of choice. So far though, you've only suggested name tags, could you provide us with some more examples as we wouldn't necessarily want to add a very bare pointshop if this were to be accepted.
