What good will a 127 mm spindle do, to avoid rubbing against the chainstay vs. chainline? Your problem was that the chainline was incorrect when the chainring was on the outside of the spider. A wider spindle will copound the chainline problem even more.

So, what's the solution? Why, a smaller chainring, or re-dish the rear wheel to push the sprocket (more commonly, but incorrectly, called "cog") more to the right. If you re-dish, you'll have to re-spacer the axle, as well. I don't know how one can do that if it's a QR skewer axle.
