Idea about running Homebrew on a Wii..., ...WITHOUT Twilight Hack or Banner Bomb

I have a little idea about the above.
You all know Brawl and the included VC-Demos, right?
Maybe Brawl has .dol-Files (or the files that appears on SD-Card after copying a VC-/WiiWare-Game) saved on the disc which includes the VC-Games.
If so, you could easily replace them and, say, run the WAD Installer via Brawl.
Or, if it uses .WADs and Autoboots them after copying them into a temporary folder in NAND, you could do it almost as easy.

Now I want to hear from you...

1 Which file type does Brawl use to run the Demos?
2 Have you tried it already/know someone who tried it already? If so...
3 has it worked? (On which Firmware? CIOS or IOS?)
4 Does the Application have access to NAND?

I want to know this because my Wii is still bricked and this came into my mind because I want to find a way to unbrick it finally. (Because burning every Wii game that I have as a Autoboot disc sucks)

Someone made a hack for running homebrew from a SSBB custom stage. It's not released yet, however.

sucks your wiis bricked :\

im using the hard drive method so i cant help you there.

Well, that could be a great successor to Twilight Hack.
Just because you could even run Homebrew without a preinstalled savegame, so you COULD even repair a banner bricked Wii! (Like mine...)

But still, I can wait a bit because I have burned my favourite games' backups (Punch Out!!, Wario Ware, Wario Land, Wii Music, and plan to do it with AC:LGTTC, SMG and SSBB, but Brawl only as soon as I have a double layer DVDR disc) now as autoboots (which thankfulls still works, but sadly none of the WAD Manager Autoboots, HBC Startup Autoboots, etc)

still glad I installed bootmii and backed up my Wii's memory to SD.

I just did that today, it gives me some peace of mind. I'm glad I got my wii when I did. Now I can install preloader without fear of bricking (I'm really cautious about doing any kind of modifications)
