I think you'd get the best result if you interline the yoke as well, especially if you go for knife pleats. Otherwise I suspect there will be a very visible seam line at the bottom of the "fell" where all the layers of the pleats are sewed to the yoke. Medium-weight non-woven fusible will probably work.
