It's plausible tbh and not the first time this rumour has surfaced, both FFVIIR and KH3 have been delayed to 2018 and Switch has so far received versions of upcoming future SE games in SOM collection, DQW 1+2 and DQXI as well as its own title in Octopath and a title in development from CT's director. Business wise the Nintendo fanbase could be sold versions of post FFVI games as well the same way the entire DQ franchise had versions reach the 3DS audience.
SE are likely aware that series like Pokemon and Monster Hunter have a high chance of hitting the NS and the userbase it generates could be tapped into further with the FF franchise.
