The reason animals are so rare is that most of them have been eaten by zombies. New buildings would be nice, but it's a lot of development work. Technically, it should be possible, but it requires someone to make all the textures and models. Prophecy, I think you underestimate the range of radios. The walkie-talkies you can get at Wal-Mart typically have a range of 500m to 1500m, depending on terrain. Military handheld radios have a range of up to 4500m. Range depends only on the transmitter, not the reciever. Anyway, most people just use Teamspeak.

I like this idea, and you've justified it pretty well, but this has been suggested before here.

ArmA 2 Free has no mod support, and it doesn't get beta patches. DayZ is dependent on several features of OA, such as backpacks. Combined Operations is $30 on Steam, and the game itself, plus DayZ, plus other mods, more than justifies the price.

Your suggestion is well thought-out, but the game isn't supposed to be balanced. NVGs are pretty rare, and a person who finds one has a massive advantage at night, just like in real life. By sniper rifle, I assume you mean the CZ550. This firearm is one of the most popular hunting rifles in Europe. Suppressors are also pretty common in Europe. I think some areas actually require them for hunting. Removing them doesn't fit with the setting of the game. Anyway, hitting a human-sized target in ARMA 2 with a scoped rifle at long range is not at all easy. If they hit you with the first shot, they're a pro. If they don't, hit the ground when you hear incoming fire.

This could be pretty entertaining, and it would make all those whiskey bottles useful. I suggest that the player need to have matches to use a molotov, and that there be a minimum range for it to break, ie, if you toss it 4 feet it won't break. The only issue is the size of the fire created. This is a good example of what it should look like:

Your claim that loot gained on regular servers gives those players a serious advantage when playing on expert servers is of questionable credibility.

Weapons needing cleaning and oiling could be an interesting mechanic, with various malfunctions when it's too dirty.

Mosin Nagant, yes please. I'll take a dozen.

We're pretty much paraphrasing what Rocket has said about the game. Besides, by posting here you effectively asked for our opinions on how this would affect the game.

I'm thinking if you had a backpack, you could probably conceal it while wearing a ghillie suit. Does this actually cause some gameplay problem? Anyway, trying to run in a ghillie suit would definitely be exhausting and dehydrating. I don't see a problem with putting this in the game.

The Bizon is chambered for 9x18mm Makarov. You should be able to refill the Bizon's magazines with Makarov rounds. Somehow, I don't think having a little more ammo for the FAL makes it OP. Using DMR mags is just going to make it so you have 2-3 magazines instead of 1.

The game's not supposed to be balanced, per se. Considering that the axe is already on your toolbelt, I don't see why you shouldn't be able to sling a long gun and take out the axe. Probably the quickest way to do this is to allow melee weapons to occupy either the primary or secondary slot. Also, the hatchet in-game is not much larger than a handgun, and it's pretty easy to improvise a holster for a hatchet.

I like the splint idea. Morphine's role in the game now is pretty unrealistic.

All the GPS receivers do is receive the signals from the satellites and compute your position. They wouldn't be capable of exchanging that information between each other.
