Kingdom Hearts II Kingdom Hearts compilation

I was on Gamefaqs today (just looking, I don't have an account) and I went to the KH2: FM+ boards, and someone posted an interesting idea http://boards.gamefaqs.com/gfaqs/genmessage.php?board=935702&topic=40470027&page=1. Basically, its a compilation of the first 3 KH games, their FM versions, and an easter egg in the form of the KH cell phone game (not Coded).

I wonder, would anyone here buy it, even though it wouldn't be on the PS2?

Remember, this is just an idea, not something that's been announced.

Oh, and I have no idea which topic this would be in, so mods, move it if you have to.
