Yeah that sounds interesting. I've never recorded stereo guitar, so it would be a learning curve, but it sounds like a good option for a situation like this. If you record them stereo, can you still pan each mic's tracks l/r in the DAW?
The hardest part of stereo recording...is getting the damn mics in place.
Both Blumlein Pair and M/S have a very close & specific arrangement...so you need the right hardware stands/sockmounts...but nothing too hard.
After that, it's no different than using a single mic.
The two recorded tracks by default are panned hard L/R...with the M/S pair, you need a "matrix" to encode/decode, but with DAWs it's very easy to set up. Some decent preamps will have it built in...so in the end, even the M/S pair, you have a Left and Right.
Now you can pan those tracks more toward center...but then you start to lose the stereo mic effect.
The real slick trick to panning a stereo guitar is to *record* it in the position where you want it to be panned, and then leave the two tracks hard Left/Right.
IOW....move the mics as you monitor the stereo mic output so the guitar ends up in the Left-to-Right spot where you want it to be in the mix....rather then altering the level of the Left/Right tracks post-recording....but, you have a lot of options, so try them all and see what works for you.
I've done a couple of songs with a lot of stereo recorded tracks...and it does eat up tracks (for me that's a PITA because I'm tracking to tape before going to DAW, and I only have 24 tape tracks)...but there is a sound to it that you will never mimic artificially, and to get close, you have to employ some delay and reverb processing...etc.
