Would it be possible to somehow construct an .iso homebrew?

[Satan]

There are tons of Wii Homebrews floating around, and I have a Wii myself but I can't be bothered to mod it, I've got Dolphin 4 on my nVIDIA SHIELD Android TV, and I'd be interesting in playing some on there...

Does anyone think it'd be possible to patch homebrew files on to a game .iso file for use in a Dolphin Emulator?
Thanks
