It's not neccesary to build a whole Scarp to have removable struts. I did a remodel of a Scarp to make the struts removable, and it was a tiny fraction of the work that would be required to do a whole tent.
Plastic caps made of arrow nocks with the tines cut off and buffed to a round shape were placed at one end of each strut. Arrow inserts with the usual 3/16" inner diameter were placed at the other end. The grosgrain strut sleeves were cut off near the canopy edge, and sewn into a loop to take shock cord. 3/16" diameter studs with caps were attached to the shock cord so they would hold the struts in the sleeves. The studs at each bottom corner were also connected by cord at the ends so the struts would not spread more than desired. That is not the whole remake, but should give you a good idea.
This job was done on the initial version of the Scarp. There were 3 problems:
(1) The sagging of the canopy was severe when the silnylon cooled; (2) The sagging of the liner was severe, period; and (3) It was hard to get this four corner tent pitched evenly taut in the first place. Worried about wind performance.
I ordered the newer version outer, and may go back to it, but only if the liner can be made taut, and elastic material can be placed at the corner guys in a way that keeps the tent reasonably taut.
This experience convinced me that silnylon needs to be used in a tunnel-hoop tent that keeps it taut, or over a dome-shaped frame that physically prevents the nylon from sagging into the living area. So I agree that a Scarp design using one of the cubens that is more water resistant and does not sag would be a great idea.
Edited 7/2 to change 1/16 to 3/16"
