Why don't you just install the same stuff on your Wii?
I don't think it's possible.
I mean, i've read about bricked Wii's using other NAND's, but i think it is pretty tricky.
Even if it is possible, it is definitely not safe.
Especially if you're a noob like me.
And it looks like you are.
I would just install the things you want.It doesn't take much time, and there are plenty of guides in here for everything you might possibly want.
Besides, if you need any help, i'm sure you will get some answers around here!
From what i hear ModMii is a good way to softmod your Wii.
Just search for that guide, it should be all you need to get started.
