Actually, now that I think about it: what would you guys like changed about this game for this rerelease? I, personally, think there needs to be a way of redistributing skill points for our characters. I know some people might not like it, but other dragon quest games let you change jobs and skills (VI and IX). I love how each character in this game has there own set of skills and weapon specializations, but picking one weapon over another is a tough commitment at the beginning of the game when the game takes roughly 60-70 hours to beat.
I would like to see a respeccing option at the church that charges money depending on your level. For example, if you are level 10 and want to test out this new sword you picked up when you already went down the spear tree, you could pay a certain amount of gold (maybe 1000g which is a good bit at that point in the game) to change your spec. They can scale it as you level up so that you have to grind the money to earn the right to respec, maybe somewhere around 20,000g at lvl 20, 30,000g at lvl 30. It will stink and cost a lot of money, but the options there if you want to take it.
