sorry, but such a config would not pass inspection.

Whaddayamean, only 4 allowed 40A devices?

All active PD Board branch circuits shall be protected from overload with an appropriate value auto resetting Snap
Action circuit breaker. Specifically,
A. Each speed controller branch circuit must be protected by one and only one 20-amp, 30-amp, or 40-amp circuit breaker on the PD Board (from the KOP or identical equivalent). No other electrical load can be connected to the breaker supplying this circuit.

[R44]
All active circuits shall be wired with appropriately sized wire:
Application Minimum wire size
40A circuit 12 AWG (2.052mm)
30A circuit 14 AWG (1.628mm)
20A circuit 18 AWG (1.024mm)[snip]

Oh, and only the CIMs and FPs are required to have speed controllers. Everything else can be run off a Spike, restricting it to 20A--but that's still 6 speed controllers, any of which can be run at 40A!
