I'll have to play around with this, I'm particularly interested in the program you have in pinephone-toolkit `cpu-sleep` to put certain CPUs offline. (Curious how that'd work out for say continuing to listen to music or something, e.g. does that still work; and is there a big battery life gain - do you have any stats for batterylife in this single-cpu/low-cpu mode?)
Also curious how manageable sway is with gestures - one problem I had with lisgd and gestures is that if your finger generally overruns multiple windows, you wind up switching window focus (atleast in dwm, and that throws off the meaning of the gesture); but curious how this worked out in your setup and how reliable it is. Will have to play around with this when I get some free time or if you wind up making an ISO that would be awesome.
To be fair putting CPUs into sleep doesn't do anything fancy, just `echo 0 > /sys/devices/system/cpu/cpu1/online` for 3 out of 4 CPUs
I don't have any statistics, but looking at the charging current it helped only slightly. I ran just one test: leaving it idling in the "sleep" mode, after 6.5 hours it had 7 % battery left, proving I could use it off the grid 
When going to sleep while playing music, there is a brief but audible skip if the player's process gets transferred to the primary CPU. Otherwise it works great and one CPU manages to play a song no problem.
Focus in sway is controlled more explicitly, so it stays where you set it. On the other hand the source touch events get propagated to the underlying windows. You may get some unwanted actions this way
I wanted to avoid diving into the problems of how to build an image with everything included, but if this PoC turns out usable, I'll reconsider it.
