Mini-mugo !

I found this at the local gardencenter. Wasn't too expensive and it already (In my opinion) has a nice trunk structure. Going to repot it tomorrow !

If you really feel like it needs repotting wait until the proper time. Like after Fathers day. If you go fooling around with roots too early you run the risk of killing the tree.

I also would not suggest repotting until summer (late summer, not sure how your climate is). Don't wash the roots.
Anyway, it's a cool tree!
