Does the snaffle have shanks? Because if it has, it's not a snaffle.. just a shank bit with a broken mouthpiece/a curb (I don't understand the ''w/''..is it with or without?) :P I've never heard of a snaffle with a chin chain, can't see the point in it, but maybe that's common in western riding?
If it's a regular snaffle (no shanks) it's more gentle than a hackamore so I don't see why you should change.
Hackamores are harsh curb bitless, don't think they're gentle just because they're not in the mouth. But the horse might very well like it better anyway, and they're not mean, they have a good/nice purpose when used in the right situation and way. But they are stronger than a snaffle.
I don't know enough about western riding to say much about pro and cons in this situation, but try it in a fenced area and you'll see how she react. If she understands the preassure on her nose there shouldn't be much differense.
Always keep your head up, but be careful to keep your nose at a friendly level.
