Hobie 21 beach roller mats?

Has anyone made any beach roller mats like on the Hobie 21? Because I was thinking it would alittle better because you could store them in your hulls if you have port holes.
Doubt they would fit in the ports. On the H21Sc there is a larger compartment to store the rollers. Maybe single pieces of pvc would work
