just wanted to report that I tried this out today. very nice - quick and smooth. my lone concern was that I had wifi problems right off the bat (ESPN streak for the CASH app). i don't think that it was an issue with your ROM though, as I tend to experience wifi issues previously (although mostly with FB or apps using FB). also, I had troubles restoring my system data via TiBu - so I'll have to go back and figure that out.
however, I did not experience any force closes when accessing launcher settings via Holo Launcher.
after I can get a better backup file created for my settings, then I'll try this again.
