LordTheNightKnight essentially wants what Sony is doing with the HD collections but on the Wii.
The question is, what can the wii add to these games while retaining the core gameplay/controls intact as to keep the nostalgia, the answer is nothing, well at least nothing meaningful to get people to re-buy games they already own.
Just look at the what Sony is doing with the HD collections, they up the resolution, up the anti-aliasing, stabilise the frame rate, add trophies, and bundle at least 2 games all for a cheap price, this is a really nice bargain and has enough incentive for people who already own the game to buy it again, it's a bargain for those that have missed out on the PS2.
Some may not like to admit it, but many will buy the HD collections for 2 reasons, the collections has trophies and the graphics of their favourite games now look cleaner than before, more so if they have a HDTV.
Just remember that these HD collections only increase the graphics by uping resolution, anti-aliasing, and frame rate, they do not actually modify the original textures. This is why it's cheap, and fast to make these collections with small teams.
Unfortunately the wii would have troubles to trying to implement the same strategy as it would lack enough incentive to make people re-buy these collections. If people want these to work, then Nintendo has to step up and prove to 3rd party that it can work and that money can be made, just as Sony has done with God of War HD collection, which is why now 3rd party are jumping on board.
Trust when I say that most 3rd partied would love to re-sell the old games, more so on the wii since the expectation is lower, so it'll just be as simple as a PS2 port to wii with nothing new, but again Nintendo has to show that it can be done, in my opinion Nintendo should prove it can be done with a non Nintendo franchise, not cuz there games sell regardless, but to prove to 3rd parties that they can sell with non nintendo characters.
Some times the platform holder has to lead the way and show 3rd parties it can be done rather than wait for 3rd to do anything, plus this is something Nintendo can do, just look at the 3DS. I say, if you really want it, then bitch at Nintendo to bring something similar to the Wii, it'll probably be more effective than bitching at 3rd party.
