Reply to Three-position potentiometer or toggle switch?

So I'm getting back to my mod project that I had to put off for my wedding and the start of my new job (oh life...), and I've been wondering what to do with the crossfader which I never use. I've dabbled with some mode settings with it and that's how I intend to map it on my controller, but there have been times where I've accidentally knocked it and thrown my mix into a freefall.

So my thought is to replace the crossfader with a potentiometer with three detents or three-position toggle switch that sends three midi messages:

0--------127
(x---o---o) = no modifier
(o---x---o) = modifier 1
(o---o---x) = modifier 2

(or something along those lines...)

Am I going about this correctly? The ideal solution would be the toggle switch--it would give me a clear indicator of which mode I'm in. I know that most three-position toggle switches are on-off-on momentary digital switches but I figured I'd ask anyway.
