I love wearing the kilt skirts. I tried on my husband's kilts, but the fit wasn't right, and at my age wearing an unbifurcated garment above the knee isn't realy attractive. For those of you over 50, think "Erma Bombeck" saggy knees and all.
I did solve the sporan problem by getting a swatch of fabric in the tartan of the skirt and making a draw-string bag that I wear around my waist.
