Can Epiphany X plug into extension cord, what loss

My dedicated 20 amps outlets are app 15 ft from my Pass X 350.5 amps which now presents a few problems for me since my Epiphany are only 2 meters long: My trouble is what would be lost by attaching a extension cord to the Xs PC since there will be 4 pcs of plug-in (non-hardwired) connections instead of 2 like in a normal set up ?
1. Moving the amps are not an option.
2. What happens if I plug the Xs into DIY DH Labs Power Plus bulk cord which is 12 guage copper. Ends made up with Wattgates. Would the X not function as normal ?
3. Or make up the entension cord with the same Romex that is inside the walls instead of the DH Labs ?
4. Or remove the 20 amp Wattgate receptales and hard wire them with Romex to the box in the wall, now the oulets will be on the floor but the Xs can be plugged in and there will be 3 pcs hardwired air tight connections per box additional to the ones in the walls to the breaker panel. Of course the electrical code is broken, however, when I move things will be restored ?
5. Or make up 2 pcs of 15 ft bulk DH Labs ?
6. And lastly and most expensive, 2 pcs new 15 ft Epiphany X which will be extremely hard for resale ?
I am not sure if anyone has gone the 'simple-complex' situation. Power amps normally prefer the least amount of solid non-arching plug in connections.
Thank you in advance for sharing your experiances.
