Uh, Torneko Taloon is awesome, sir. He basically is an NPC that you happen to play as, a merchant family man that saves the day with his good business skills. Plus he's the guy that started the entire Mystery Dungeon series.
As for DQ7 remake, that's a little odd. Besides the original trilogy and iOS ports, it's actually the most recent game in the series to get remade (the 2015 3DS remake) so it'd be weird to get another remake of it.
I'd rather them just go in order. No reason why they can't remake 4 or 5 in HD2D next. Those are both more popular than 7 anyway.
