Brogues (not Ghillie) have been worn with kilts, at least in the British Army, for quite a long time. I own a pair of MOD pipers brogues in a heavily grained black leather, as well as a pair of Loakes brogues in a smooth leather. These are what I typically wear in dressier situations, the latter being lighter and more comfortable than the former. Buckle brogues are also quite traditional. I've also worn "monk" style buckle shoes and I think they look quite good. You might also look into semi-brogues which only have a little broguing on them. I'm not sure a cap toe oxford would look quite right with a kilt.
