PPD Portable?

Hi guys. I know that psp is already have Diva game but isn't this will be cool if PPD would be converted into psp game) we can turn our psp into mini aracade machine. How do you think is this even possible. I have diva on psp but I want to add my own songs and use skins like arcade can. If only someone could make a homebrew like this. I mean c'mon some people was even able to make minecraft for psp :D
So what do you think of this idea?

Not a bad idea, but most songs for PPD are oriented to the Arcade ver., and the buttons aren't in the same position as in the PSP. Imagine having to hold 3 buttons at the same time and having to push quickly the fourth one. On PSP it would be very difficult (not saying almost impossible).

Arcade buttons: Triangle Square Cross Circle

PSP: Up Triangle
Left Right Square Circle
Down Cross
