Yes, as long as you're layering Snapback on top of other sounds, rather than directly sampling its output on its own (ie, resampling its onboard samples in isolation), then you can use Snapback for any purpose you like.
Snapback isn't processing the input signal in any way – it's layering other sounds on top of it, so there is no dry or wet signal per se.
Please use the Snapback and Transient volume levels, and the source mixer channel's volume fader, to balance the mix of input signal and Snapback/Transient levels. You can also use Snapback on an auxiliary return channel, of course, and route the input signal to it via your mixer's send controls.
