It can't happen, you could look for a custom ROM on the XDA forum, but as you are probably aware android Icecream sandwich slowed down your phone quite a bit. The experience with lollipop will be terrible, that's assuming that there's such a custom ROM

to be honest you get a far better experience with Android 2.3 Gingerbread than 4.0 or possible newer flavors/updates but check this out

http://forum.xda-developers.com/xperia-mini

you should be able to find custom ROMs there.
