I like this, and it’s very similar to what I have been thinking of. On the power side, I am considering doing power distribution at the top. You can retain IP based power control if you use something like a PacketFlux 5ch PDU with a SiteMonitor. Both are tiny and could likely fit in the same enclosure as your fiber. You would however have to run a single CAT5 up the tower for the SiteMonitor.
