Triple Source acoustic guitar pickup — worth it?

[Victor Gwee]

I have a Fishman Presys Blend pre-installed in my Custom Acoustic FG92CEQ (full solid sitka spruce + rosewood). This gives a mono output with adjustable piezo + mic mix.

Am wondering if it's worth the effort to include a third pickup (SBT or magnetic pickup) to make it a stereo output. This can be split and fed into my Zoom A3 preamp to blend all 3 pickups.

Thoughts? Is dual source + modelling enough or will triple source + modelling capture the tone of my guitar better? SBT or magnetic?

Now I'm not sure whether I'm pursuing this too far. Perhaps there may be an audible difference when recording but not playing live?

Either way, my itchy fingers have led me to buy a few no-brand cheap SBTs from online. See how it goes lah...
