Hmm, if those barrels double the firing rate (which is not the case for rotary weapons), then yes, in a way that is so. Double-barrel shotguns - if operated by a single trigger (most have two, or one trigger that fires them independently) - actually are a very good example of a twinlinked weapon, as there is little conceptual difference to a storm bolter if you get down to the details.
It boils down to what exactly would you consider as "twinlinked". By your own definition (and the description as given in the book), a double-barrel shotgun would apply for this just as much as a storm bolter.

Gravity. At some point the armour - whilst physically able to carry the weight of such a monstrum - will just topple over (unless maglocked to a metallic surface). Aside from serious impracticability of not fitting through doors, into vehicles, etc.

That's a way better example, yes. Also in terms of how it seems to look.
