Final Fantasy XV port in Unreal Engine 4? To be honest I'd think they'd be better off making the next Final Fantasy game with a Switch version in mind from the start of development, would probably be a lot easier ....although by that time the Switch 2 could be on it's way out.
An exclusive Final Fantasy spin-off kinda game on Switch which is less demanding and re-uses assets of Final Fantasy XV with a new story based of that game could maybe also work.
