To be fair Mr strife didn't have the need for his 7 sword motorcycle or his back mounted weapon store until advent children hit it big. It would've made sense to me to have a "strife outfit" and/or an "advent strife outfit" to pick from (especially since in advent children he used multiple swords as opposed to the Buster Sword) but seeing the 3x repeated lightning event that's sole purpose was to hype up the XIII franchise I can only assume we got the ff7 remake outfit to hype that up too
