Is there any way to change the on-screen soft keys to look them like that of Nexus 5 lollipop soft keys.They look really cool and other thing is the transparency of the on screen buttons.It would be great if you made this above mod in the new ROM

But, there is a way to get that transparency, icons and all that, in the Xperia ROM. You will have to install the Xposed framework, install GravityBox and then mess around with the tweaks in that to get that effect you're looking for.
The Android L ROM will have all that navigation bar tweaks and things you're looking for, so I'll try to extract that and add it to most of the ROMs.
Note : If you're unwilling to pay for the app, just do a quick Google search and you'll find the apk file, which can be downloaded and installed manually on your device. Either that or you could download the app through Blackmart Store for free.
