Thinking back at this, I searched for a mod, but found none.

I was curious why, but then, after some digging on forums and mod's sites,
I see it's probably because of copyrights

So I had an idea (two to be correct), feeling nostalgic for portal and core’s appearance in Skyrim's world :

Why doesn't Space Core (or any other) "comes back" as :

1) Dwarven Centurion Master-based Boss Fight, moded in its torso or head,
along with a good story to back-it-up,
like he has escaped from Dragonborn's inventrory and gone mad for power once more,
after seeing that this world is populated by lesser beings,
planning to take over and rule the planet as the new master of the Dwarvens Automatons !!!
(This could even be build by moders if Valve would give premission)

2) A Follower, modded on a Dwemer Sphere, transforming to a warrior in attack-mode to defend the Dragonborn and back to a sphere when in non-fighting mode, following him / her (or even ported as-is form "Portal 2", if possible ) ?

The Core could be attached to mechanical arms to follow the player and to the "body" for the final boss battle on "Portal" game, as well the two co-op players got bodies (Atlas and P-Body) in "Portal 2".

Why not here to ????

So, as a question to Valve :
Could you please make a DLC with a...“Core-nturion”
Or / as well allow moders to make mods with our favorite Cores and/or Co-op bodies ???
