Possible to upgrade to WM6 or down to WM2003 from WM5?

Im running Windows Mobile 5 on my Universal. I havent done any ROM ungrades to it and wanted to know if its possible to install WM2003 (which i prefer) or WM6 on it, and if so, where do i get the files?
Can someone recommend any upgrades that I could perform anyway, eg ROMS, Radio, etc?
I appreciate any help
Thanks

There is no WM 2003 for Uni, check WM6 section
