I'd like to see them stylistically different from the Inner-Sphere. I could say "more futuristic", but I'm unsure of where that would really go. More aerodynamic? Streamlined modularity? *shrugs helplessly* The fact that they swap modules and have many interchangeable parts makes me feel that they would look far newer in looks to Innersphere battlemechs as well.
There is one thing I do know: the Clans built themselves a mythology, with each clan symbol a 'totem animal'. This makes me feel I want to see something more primal in them - clanners are supposedly amazing mechwarriors and this makes me feel that when a Clan Omnimech could move, it could feel more like strides, stalks... rather than being as mechanically ponderous as the Innersphere mechs.The angles, the way they are built needs to feel more foreign and predatory.
When the clans showed up, the Innersphere warriors took them for aliens. The mechs, to thier eyes, felt 'out there'. it was more than just a matter of performance (though it helped). I do remember my first contact with the Clans to have been in Battletech 2: The Crescent Hawks' Revenge. When I saw the first icons for the Puma, Blackhawk and Mad Cat... they were like nothing I had ever seen. When I saw the actual art for them... i didn't feel it lived up to the impression I had - they looked too ordinary. The Timber Wolf/Mad Cat is a great mech design, but if you just look at the visuals of it... if you show it to someone ignorant of the BTech universe it might be considered a cool mech but there's nothing that screams 'different' if it sits along with other IS mechs.
edit: actually, the IIC mechs in the tech manual look believably more 'clan' than many clan mechs. If the clan mech design could get stylistic tweaks in that direction, it might be nice.
