Signalman's connection to the Carranger is not the same as a 6th Heroes. If there were a 6th Carranger, they would have some sort of power/ability that would tie/connect to the Kurumagic of the team.

Signalman is an alien officer from a police civilization using the technology of their world which does not have any magic whatsoever. You could argue that Radietta is closer to a Carranger than Signalman, mostly because at least her powers are tied to magic, albeit more along the lines of the magic of the planet Fanbelt than the magic of a constellation.
