I like what you've said, but you're drawing the wrong conclusions. Porting that from it's intended system to another can make gameplay difficult and frustrating, but not always. A game doesn't neccisarily rely on it's initial control design for ideal gameplay. I loathed Oblivion on my computer and I can't IMAGINE playing a game like Command and Conquer on a console. But when Doom was ported to allow mouse use, and strafing? Doom became one of the easiest FPS I'd ever played. (Turn your y-axis to nearly 0) There is no 'one ideal' control set for games, but it's generally accepted that mouse/keyboard combination is the superior combination for FPS.
A great example, there HAS been some cross-console gameplay in the past to set precedent for this. MS released a game a while back in 2007 called Shadowrun (terrible game), and allowed 360 users to go head to head against their PC counterparts. Balancing was an issue between PC and 360 and so MS, "implemented a feature which causes the cross-hair to expand during quick movements, thus lowering the player's accuracy... making it impossible to quickly turn and maintain accuracy, reducing the potential advantage of playing with a mouse". This was originally on Shadowrun's website, now found on wikipedia as an excerpt.
