Custom ESCs?

[Unsullied_Spy]

I'm looking for an ESC for my micro Desert Truck and have been eyeing the 1/18th scale Sidewinder but it's a bit big and the wires are longer and thicker than they need to be. Would it be possible to get essentially the same ESC but more compact with smaller and shorter wires? It only needs to be able to handle 5-6 amps continuous and about 10 amps peak.
