Front Mission
Square Enix tried and failed to do a new entry within the Front Mission series with the ill-fated Left Alive back in 2019. Perhaps the play, then, is to let Forever Entertainment take a stab at remaking a few games within the franchise?
There are a lot of possible different ways Square Enix and Forever Entertainment could approach remaking Front Mission. Sticking within the spin-off series of games such as Front Mission Evolved would be the safe pick, and would likely be something that Forever Entertainment could easily handle.
However, the more impactful choice, of course, would be Square Enix allowing Forever Entertainment to work on the original series of tactical-RPGs from the PS1 and PS2 era, Front Missions 1-3, or even 1-5. As long as everyone involved is comfortable with it, that would be great to see.
