I have an old mid length receiver ("J" series) 110 that is right hand. In light of the right bolt left port variations that are out, would it be possible for me to put a LH bolt (in a LH stock of course) and use the RH head for right port ejection?

The reason I ask is I shoot LH and this rifle has a lot of sentimental value and would like to use it more. I CAN shoot it LH as is but it would be a lot slicker with a LH bolt right port setup.
