Game Mechanic differences between Mechformers and Beastformers

Something that may help balance out the factions would be to make some differences between the factions other than alt modes (and all that entails). We could get really involved but some simple differences could help with the feel of differences. Though if this idea got done we would have to be careful not to overdo it.
So what does everyone think of the basic idea and its feasibility at being added to the game at a later time?
Autobot/Decepticons
Maybe a ghost strength point. This could represent a variety of things, the mechanical advantage that being 3+ times larger (longer limbs,more mass) on average, and even that they have raw power (much less effient)in thier power systems. That last point (if str continues to help all weapons) can represent a variety of components that require space.
We can take the approach (my personal viewpoint I admit) that the beastformers are more advanced and so can reach approximently the same power range with MUCH smaller and more effient bodies but there are tradeoffs.
Maximals/Predicons
I lean toward several smaller bonuses.
These factions could have lower CR costs. Maybe have the ability to heal slowly without the CR. Get bonuses on certain missions that a small size would help. Maybe lower energon costs on something else such as armor installation either including the cost of armor or not I can see it either way.
People who are constantly haveing energon issues may prefer haveing a slightly less powerful character but haveing less of an issue staying in the black.
