Do you mean slightly oversized plugs to force into old usb sockets? I don't know how you'd even supply chain that, being that the changes are probably within the tolerance envelope, or you are breaking the standard and that is far from a good idea. I also don't think this is usually the problem. In my experience it has been less the socket getting stretched and more it getting packed up with dust so the clips don't engage properly. Cleaning out the port tends to solve the problem.
If the port is actually mangled, better to do a proper fix on it. Because we stick to the standard the part cost is minimal so even if you are going to a tech you are mainly just paying labour and rent.
