Some leisure kilts in Europe just have two kick pleats at each side and none at the back, so they are more comfortable for sitting. So long as they have overlapping front aprons I think you could accept these as kilts.
Knee length jeans skirts with no pleats and front zipper flies are available in men's sizes and men's waist/hip proportions in England, when I have worn these I have occasionally been complemented on my "modern style kilt", and indeed wearing a jeans skirt in Toronto and in Vancouver several people asked me if I was Scottish. The only person who appeared to know the difference and call it a skirt was a kilt wearer whom I met in an airport. Jeans skirts are definitely not kilts.
