I agree with a couple in the OP. (for the most part I don't think 2D games need remakes)
An official remake of Simon's Quest that fixes the translation and slow text every time it switches between day and night would be cool.
Mega Man Legends (I'd rather get MML3 but I'd definitely take a remake as well)
Dino Crisis (they could probably just use the RE2/3 remake engine for this, so yeah get on it Capcom)
I would like a Xenogears remake, one that fixes the second disc(basically turned into a visual novel because it ran out of time/budget). I would be good with AAA graphics that would probably mean it needs to be multiple parts like FF7R or a modest budget.
F-Zero GX - just needs to be remastered and have online play added. Maybe on Nintendo's next console though, I don't think Switch could handle online play for it at 60fps. lol
Super Mario RPG - A remake of this with some new content and a higher difficulty option would be sweet.
Fire Emblem: Path of Radiance - Even just a straight HD remaster would be fine so there is a cheaper way to get this game. (it's $150+ on Gamecube)
