Unity3D Carousel Menu for A game targeting iOS, Android and WP8 (WebPlayer too perhaps)

We want a circular scroller in Unity 5 with NGUI 2.7 free edition, for Android, iOS and Windows Phone platforms. This will be a circular animation – meaning when the last element is reached, it can continue rotating and it will show the first element next to it, again. When the user will swipe right to left on the menu area, it will move the current image, which is on top, to the left and the image which is in right (below the top image) will become the current image on top. Left to right swipe will also work in similar fashion. Also, clicking on any image behind the front one, should make that front image simulating the same way if someone would have swiped for that action. Please note that since its a MENU, each image will have a "Click" handler associated to launch its selection. Images can be present in either in Resources folder or in Assets folder or could be downloaded from web on-the-fly and can be added to the scroller from Unity UI (inspector) or also from code. Any image should be allowed to change anytime on-the-fly and scroller should immediately show up the changes on the UI without the need to reinitialise the whole scroller again. Images can be in transparent PNG or .JPG or JIF format and can also be present in the NGUI Atlas format. Having some parameter to configure how many images to show at a time, 3, 5 or 7 or whatever would be great. At minimum we need option for 3, 4 and 5 options. The left and right side images will be tilted and shrunk in size to show it more appealing giving little 3d look. When moving from left to right or vice-versa the image shape and size should be change to normal gradually, to show it animated way. As we want to integrate this in separate project so it has to be in a very modular / structured way. It will run on mobile platform, so memory optimisation and speed will also have to be taken care. We prefer to use NGUI's in-built tween classes as opposed to use any other tweening library, as it may not work well on all platforms with that as well we don't want to make our binary heavy just by adding another library. Attached is the animated SWF to show what we are trying to achieve. Feel free to ask any question you may have regarding the project.
