Good luck with that. People have started petitions before to try and get the iTunes LP experience on iPads, that was back over three years ago when the first iPad was released and Apple still hasn't done anything. I hate to say it but you could have a million people sign the petition and Apple likely won't do anything. The hardware in the iPad 2 (and above), iPhone 4s (and above), and 5G iPod touch are more than powerful enough to run iTunes LP and iTunes Extras and they have displays big enough to enjoy said content. However, Apple hasn't added support for those devices after all these years. That's a good indication that they won't.
