The Renaissance is considered to cover roughly the 1300s through 1500s, so any form of the kilt would be restricted to the feileadh mor -- and that would only fit the latter half of the 1500s.

If you want to be "period correct" for the Renaissance, your best bet as a Scottish Gael would be Irish attire of the same period -- a leine and brat -- as the Irish and Scottish Gael dressed essentially the same way through that era.

EDIT: Oh, and the baskethilt broadsword only came on the scene for the Highland Gael in the mid-to-late 1500s: It, the belted plaid, and the Great Highland Bagpipe all seem to have come into prominence at about the same time, or at least in the same century.
