I haven't on these yet, but I occasionally "re-work" connectors on things. Sometimes the engineers need to be given a little slap. They make a connector so fragile that it should only be plugged in once and left there, and also make it proprietary so you can't just grab another off the shelf. Sure(If memory serves me) these power supplies are big bricks, and probably making it so you have a good enough one, not just whatever's laying around, but still, I'm mainly just generally speaking for electronics.
If you're going to put another male/female in-line of the power adapter, just make sure you're 100% on the wiring, and how many are being used, as sometimes there's feedback wires, unused wires, etc. Also find a good spot to securely mount whatever is going to hold the pig-tail that you're putting the new end on, and some way to not make the original connector stay connected and not keep getting bumped in transit/storage, which can be just as bad as the original problem, making it like a crow-bar on the jack.
