Yes it should, but you'd have to re-name the NAM folders and everything else too. The requirement to use the z____ is because the NAM contains two folders. Network Addon Mod, the base mod, and z___NAM which contains overrides for the former. It's the use of the underscore that's important, SC4 will generally load that character after every other. So z___NAM was used to try and stop users complaining the NAM wasn't working, when in fact other mods were interfering with it. Sadly this sort of backfired, as some have put it "It's caused a load order arms-race", which isn't really helpful. The problem is, most users don't want to understand the whole load order thing, so solutions like this are necessary to avoid an unreasonable number of support requests. See "Where's my water?".
