Looking for some help with a potential swap idea

I’m wondering if it is possible to put a 6 speed manual from a USDM Legacy Spec B into a 05-09 outback with the 3.0R motor. I understand that the AUDM Liberty Spec B had the 3.0 in it and a 6 speed, but I’m not sure if the USDM counterparts bolt up. I would also like to know how much electrical work would be involved to put the 6 speed manual in a car that came with a 5 speed auto (speed sensors, reverse lights, stuff like that).
