Shortening or lengthening wire on Neu/Castle 2200kV motor...is it ok?

[Chadworkz]

My ESC was mounted to the top of my transmission in my Revo (nitro conversion), and when the truck flipped over and slid down the road, it ground through all three motor wires...is it OK to remove the bad section of wire and solder the two ends of each wire back together?

Also, I would like to move the ESC to a custom carbon-fiber tray I built, but the motor wires are about an inch too short...is it OK to lengthen the wires by about an inch or so?

Thanks in advance for any help you can provide.
