Well, there'a already a blowhole_penetration tag. It doesn't have many entries though, which is kinda odd now that I think about it. There are plenty of cetacean images, so you'd think it'd be more common. Such a shame. =(

As for as the decapitation blowjob tag idea, how would it be worded? There's already a bit of messy tagging in the decapitation/severed head/detachable head area. Nadia Fortune is a great example of this. Her head is technically detachable, but the severed head tag gets added by mistake sometimes. Maybe something like "headjob" would work, and just add a note to the wiki to include both severed and detachable heads?

Perhaps a combination of wound_penetration and decapitation? head-job has too many possible alternative meanings. neckstump_job might make sense for fucking a decapitated throat...

Either way, I'm definitely not touching any of those images.
