In sequencer mode, you can have as many drum tracks as you want... so there's no reason to give up the rest of the kit to get the snare sound you want if it is not available by Makeup Tools...

Oh, and I think I'd just layer it in the background, rather than replace the snare outright. To a certain extent, the basic sound is 'sound' it just needs some extra 'pop' to make it more timbrally dynamic, IMO...

You could 'copy' just the snare note, paste into another MIDI track, and then Makeup Tool (or transpose) it to be the snare sound you want. Then a volume command (not reducing the velocity) will sit it in the mix without losing the full dynamic range...

Hope this helps.
