Early ranged stun would be nice, but I thought the idea was that ranged stun should be bad early on to favor the more risky "rush in for captures". The harpoon gun is usable once you get decent firers to actually hit, maybe some buff in armor penetration for the darts (you only need a scratch for the tranquilizer to work) and a blowdart version could work?
Depending on the range, bolas could be really neat or not really all that interesting. The whip is a "ranged" stunner and also suffers from this. Unless bolas are really useless (at which point why implement them?), I can hardly see an implementation of bolas that wouldn't make the whip entirely redundant (it is already often better to take 2-3 extra steps and hit the people with a handle).
In my experience (now 3 years in), throwing weapons are actually really good. I regularly use javelins and fuso knives even with my main team because there is nothing that is approaching the kind of damage they deal without having a significantly higher price/shot, especially one handed ( I did increase the range of the javelin by changing its maxRange into a aimRange though, with severe accuracy loss past it. Although given the accuracy multiplier, it isn't too much of an issue). Even Disc'o'Death were discarded as "too expensive and bulky" compared to the lowly Fuso knives, as the gals could achieve similar damage values and knives are cheap. Bow scaling and arcing shots also keeps them relevant through significant advances in gun tech.
