Is it possible Pike was simply really messed up?
I'm sure he didn't even exist from waist down. Heck, I'm not sure he existed
at all, considering so much about the SB 11 action was downright illusory or potentially done under the influence of the Talosians. Perhaps Pike had died recently or even decades ago, and the Talosians simply lured Kirk to Talos in order to complete their slave-breeding mission (Kirk never noticed half a dozen of his best yeomen of either sex went missing).
If Pike lived, though, he might have been not just physically totally crippled, but also brain-damaged in the sense of having lost the ability to use language. The suitably enlightened McCoy would definitely still see his "mind" remains in there, intact and aware, but no mere voice synthesizer would ever allow it to speak its piece.
Regarding TAS, the shuttle flight deck seen there has different dimensions from those seen in TOS, but both might be taken with a grain of salt, considering the forced perspective and the shortcomings of animation. In terms of stowage, there ought to be plenty of space for spacecraft sized like vans; TAS is problematic because when the shuttles do see use, the interiors make them seem
much larger than that.
Finney manages to evade a full search in Court Martial but in Day of the Dove, "taking Engineering" seems to be limited to that one general set.
Not only Finney but Evil Kirk exploits the two major characteristics of Engineering in evidence:
1) It's a vast maze
2) It's almost completely empty of personnel under normal circumstances
The second factor would make it easy for the Klingons to take control of Engineering, the vastness being no factor in that. At worst, a single hapless Grease Monkey, Second Class might be left behind the twenty-second beer barrel from starboard - but if he or she attempted valiant sabotage, whatever the * creature did would negate that sabotage right away, and if he or she attempted attack against the Klingons, a cycle of swift death and frustrating rebirth would follow...
