This is a good idea, and I wouldn't object.
To digress for a moment; does anyone think that the arsenal in the game could be slightly altered; e.g. restrict M249s to a total of 10/8/5/whatever; allow AWPs to a total of 10/8/5/whatever, etc. Let's be honest, two persons camping in long tubes with two Paras doesn't allow for a fair opportunity for zombies in the present state of the zombie classes and attributes, which goes back to DarkRavin's argument of how the deformed could stand to be upgraded, more HP, faster, etc.
In my opinion this would make the game more challenging and also present more options on different maps (e.g. long-distance firing). Let's be realistic, the AWP itself is not an effective weapon against zombies; while it does deal significant damage, its bolt-action mechanism is slow in operation and it does not create significant blow-back (compared to say the 12-gauge pump-action)
