Making automatic universal android ROM flashing tool without root

Here is the "old" problem I discovered. Maybe this is idea for startup what you think?

Yesterday I had a pain of flashing my old samsung android phone with MIUI ROM for 5 hours, as doing that for the first time I need:

- backup info: files + apps and especially apps data (say to play angry birds on the same level) - find tools and how to do that - make root - same - find correct ROM - install drivers - choose correct flash tool - flash, restore backups, setting etc

It is boring I think. Is there is the tools making all this process automat for different tablets/phones (most popular) ? So just plug device through usb press few buttons and fantastically you have same phone, new rom, same data+settings+apps.
