Perlmutter then had the TV division resurrect the project in what was a very high profile manner, including a limited theatrical release for the premiere. Perlmutter was also the one behind the big push on the Inhumans in the comics at around that same time.
I thought the comics and AoS/MCU push for the inclusion of Inhumans was because they didn't have cinematic rights to use the X-Men at the time, and then once those rights were returned their was no need to have the Inhumans take their place.
