Yes the ends may be changed. As for concerns about fluid, the newest Purist Audio cables are filled with Contego, not fluid.
Anyway, the fluid or Contego stops a few inches from the termination point with a flexible section. The seal is not broken when the plugs are swapped in either design.
I imagine almost any cable from any audiophile builder could be special ordered with plugs of your choice. Common example is approved male terminations for Japan or Europe.
I have changed male plugs on several brands of cables, including Purist, from 120V to 240V and back again. If your interested in a specific brand (as opposed to voltage-design), again, it is likely any builder would accommodate you for cost of material when assembling your order.
