In regards to FrostBite (thanks for making me remember), I know that DKM has some stationary rocket launchers and that the guy lays down to use them (I think, anyways) which tells me I can do my own animations. Shouldn't be hard.
As for woofer, I don't know that that is possible without fancy scripting. For simplicity and compatibility with 1.46 I will be doing limited ammo count on the weapon. 4 shot clips, 4 clips (1 in weapon, 3 inventory). So pick your shots wisely.
