Note that Phil Saunders was only a concept artist who was responsible for designing the suit's appearance instead of the functional aspects of the suit. In the article you cited, Saunders talks about, for example, the shape of the suit, in "...traditional cut lines if you can vary the hardness and flexibility of your material at will", or how the material of the suit would appear, in "...the right balance of organic to mechanical to keep the feel of an Iron Man suit", but never once talks about the mechanics of the suit. As such, you are only correct as far as the appearance of MK-L is concerned (unless concept artists also have a hand in writing, in which case, I apologise).

Bleeding Edge, as it appears in the comics, has a much wider arsenal of weaponry than MK L. Its repulsor weaponry is not limited to a chest or palm-beam but BE could also shoot it out of its eyes or even curve beams when manifesting various powerful solid-energy weaponry such as energy blades and force fields. It possesses a number of tactical equipment which could have come into play in IW such as sonic weaponry. It could also shapeshift, resulting in the armour's capability to be stored in the hollow of IM's bones, but that is used much less extensively in comparison to the other functionalities of the armour.

On the other hand, MK-L has a much smaller range of repulsor weaponry compared to the above, instead relying extensively on its shapeshifting in fights. It could form powerful thrusters, can summon missiles in its backside as well as siphon more mass into its limbs for the infliction of greater physical trauma. This mirrors the Model Prime armour as it appears in the comics, especially in its ability to shapeshift -- MP is seen de-manifesting into nanobots then manifesting back into a suit at a moment's notice, manifesting a physical blade, and even missiles (which come out of its back, just as MK-L's). It also has a repulsor weaponry which is much less expansive in comparison to BE, much like MK-L, and is housed in a certain housing unit, just as MK-L is, instead of within IM's own body.

This all points to one thing -- that MK-L is (at least to an extent) based on Model Prime. Numerous other websites have also compared MK-L to Model Prime. It isn't only a speculation on my part.
