Would a binary file in each /proc/PID directory containing just the right
information for /proc be ok?

I minor tweak to "top" and procfs would fix that 50% CPU time in the
usual case. All you need is for readdir("/proc") to return the processes
in approximate reverse order of CPU usage, and to have another file
which reports idle time. Then "top" can stop reading once it's reached
a total of 100% CPU usage.
