well, according to code all splices and terminations are to be in an enclosed junction box - that puts the idea of using butt splices out the window. AND you (can't) just wirenut pieces of cable onto the stubs. next option would be to follow the wire backwards to a junction box and pull a new feeder and/or go back to the first outlet the cable feeds and pull in a new feeder to the outlet string. where the wire goes to a switch - it may be a little difficult to snake a wire up into the wall so where the wire does go through the floor, put a junction box here and splice on and run the feeder to the panel. just mind you that you take care and use wire of the proper - same gauge you are splicing onto.
