So I thought I might update you guys on how my stance worked out after moving the front binding wider and leaving the back one at reference. Everything felt good going down and all was well... until I started to initiate toe/heel side turns. There was a noticeable difference. Basically, it felt like I was riding switch when I wasn't. Was very uncomfortable for me so I had to change the stance. This time, I moved the front back to the reference and put the back binding one set wider. Worked out great. However, since my board is a slightly set-back twin, doing this made my tail pretty damn short. Ollying was of course poppy because of this, but I lost some stability. Something I am able to live with considering how much better the 22'' stance feels compared to the reference 21''.
So the moral of the story is, if you don't move your bindings in unison with each other, the board's geometry is noticeably affected.
