Would anybody else like unlockable extras?

Sort of similar to Reach, but instead of credits, you would have to accomplish tasks. Some examples would be Grunt Birthday Party when you did of headshot. A RvB themed one where when you honk the Warthog, it plays Mexican music. Etc.

What are your thoughts/ideas?

I would be happy to see Grunt Birthday Party in Halo 5, however what I truly want to see in halo 5 is Grunt Funeral. I adore that skull, b/c its hilarious to watch the grunts explode, which saves you a lot of time.

EDIT: I apologize, but I’m not sure if you were referring to Skulls or Easter Eggs?

He’s referring to Armor Effects. Grunt Birthday Party, Pestilence, Inclement Weather, Flaming Ninjas and all that.
