I have no issue with the concept of a corporate tartan. I do think that the OP may be over estimating how many of his fellow employees are interested in wearing a tradition kilt made in the tartan. (While it may be hard to believe not all are as enthusiastic about kilt wearing as XMarkers). He obviously is and is very enthusiastic about it, but I suspect he would be in the minority at his work place, just as in the Scottish highlands where kilt wearing is "legitimate" and "normal" at least for special occasions, unless you belong to a pipe band or are participating in Highland games.
Perhaps the OP should consider starting a company pipe band and as a way of promoting the use of the few corporate tartan and the actual wearing of the kilt.
Cheers....
