Hi Rick,
reading your requirements and wish to eradicate he pesky warts from your
life...
My first thought was to use R-Pi PoE HAT. However, seems that there is a
problem with their function and AFAIK they have been recalled/put on hold.
A practical (and may be even cheaper) alternative to the HAT would be to
use a PoE splitter with a 5V 2.4A supply (4 pack on amazon < CAD 10 ea).
Use the already existing Cat5 cabling, add a suitable PoE supply unit
and hook up as many of your Pi's as the PoE adapter allows.

Haven't tried it myself - but that might be one way to solve what you
would like to achieve.
