PokeWalker Question: A way to start a new game and keep Pokemon?

[Ar7ific1al]

For quite a few months now, I've been unable to play my Heart Gold because, for some idiotic reason, I used the Walk through Walls code and spoke to the lady at the GTS from the position in the wall behind her. Now, I can't load my save, because the position where I saved is not a valid set of coordinates on the map. And seeing as how there is absolutely no way to fix it other than to buy something to dump the save and modify it directly with PokeSav (which I'd like to avoid, as spending money isn't an option for me), I was thinking about the PokeWalker.

I'm aware that if you start a new game, you lose ALL Pokewalker data once you save the new game. However, what I would like to know is: is it possible to trick the PokeWalker into thinking it's connecting to the same game save?

My suggestion is to input my OT, ID, and SID values into the correct boxes on PokeSav, generate an AR code, then start a new game. Then once I start the new game, activate the code so my new OT, ID, and SSID are overwritten with my original. Then, would it be possible to use the Pokewalker with that gamesave as if nothing happened??

I don't care if I lose the courses. The Pokemon is what is important to me. I have a very special Pokemon that I absolutely DO NOT want to lose. So I was thinking that if this is possible, I could load it on the walker, start a new game, and use the AR code to set my info back to how it was before the new game.

Please, someone look into this, as it's way too risky for me. I ABSOLUTELY DO NOT want to lose this very special Pokemon given to me by someone very close to me.
