This will probably happen anyway. Research ships are manned by researchers (usually of the non-bureaucratic variety) and in my experience are game for a laugh. Regardless of what it gets officially named, this ship will almost certainly be unofficially referred to as Boaty McBoatface by its crew.

(And as another commenter who is familiar with the project internals pointed out - they already do call it McBoatface)
