Fully agree with 2,7kHz and 500Hz 5 pole filters being sufficient.
Add there 6 kHz for AM and (15 kHz) FM, if needed.

I think 5 was a good estimate, after all.

I have not seen it mentioned yet, but the best installation of open wire
line will tension the conductors between 2 supports. That means fewer
spacers are required because the tensioned wires do not sway as much in
the wind.
For my part, PVC spacers are easy to construct and inexpensive.
As long as the roofing filters are placed in bandwidth order, can filter slots
be bypassed in anticipation of placing filters in the slots later? For example:
Slot #1 Not used - reserved for FM filter
Slot #2 6Khz
Slot #3 2.7 Khz
Slot #4 Not used - reserved for future filter
