DIY Ultra Battery Saving mode?

I'd love to have a mode on my N5 that would be battery friendly. My idea is that the mode would:
  1. Lower max CPU clock speeds/disable cores
  2. Lower the resolution of screen to 540p
  3. Disable background everything

First can be done with Tasker+Kernel Adiutor, second with Tasker and command "wm size 960x540", for third I'm not sure. But the problem is that the second one would screw all the homescreen icons, so I am thinking that maybe you should firstly switch to second user, then turn on this mode, reboot, use second user for as long as you want, when you think you need to go back to performance, switch off this mode and reboot (I think wm size command needs a reboot).

But maybe there are some more efficient ways? I was thinking of dual booting "normal" and battery_saver_constantly_turned_on ROMS, but that may require of syncing battery saver ROM a lot after it has booted (if you don't use it a lot) and that would eat lots of battery.

And now I may have found the third and the best option – to not just only change the size, but density too, so that it wouldn't screw with my homescreen icons!

If anyone has better ideas, I'm interested. And after I succeed I'll probably make a tutorial too.
