"Superscroll" function in library list mode (analog-triggers sensitivity)?

Hello, just a quick suggestion, I have no technical expertise of any kind and have no idea if this would be easy to do.

I am the owner of an antiquated Phillips HDD100 mp3 player I find the method of scrolling to be very good, and would be worthwhile having in XBMC at least for me and my music.
The phillips patented Superscroll method- Light pressure on the scroll buttons causes menus and lists to scroll slowly, while additional pressure accelerates the scrolling process while the first letter of the list is shown in a large font on the screen.
