If drag is your issue, what about trying to change the bottom of your sled rather than going through all the extra effort.
Drag is a result of surface area, pressure/sq inch, and the friction coefficient of the two materials in contact. I doubt adding skis will help because of less surface area in contact as the pressure on every square inch of the skis will be much higher than on the sled bottom. Your gain will likely be because of the friction coefficient of the skis on snow/ice.
I'm not a skier, so don't know all that is done to make skis slick, but isn't there a wax applied to the bottom of skis? Could not the bottom of your sled by waxed periodically to achieve the same result without building onto it? Or teflon slids like are used some boat trailer pads?
