I don't see why not. The only thing I wondered about was whether the distance ability does anything to touch attacks at close range, but I imagine that has been hashed out in another thread. I don't see anything indicating it changes it in any way, so really there's nothing to worry about.
I understand that by "tweaking" you mean just replacing the word "bow" with the word "firearm," and the word "arrow" with the word "bullet," so don't think that needed attention.
