One thing I've been thinking about, no less from the apparent lack of E6 character examples in the 'optimizing E6 campaigns' thread and Rya's comment about stat blocks not being fun.
Is there a better way to list E6 charaters? I mean, instead of writing weapon focus, greater weapon focus and power attack, cleave, great cleave - would it be better just to write greater weapon focus and great cleave. The prereq feats are included since you must have them, but their benefits are included in the better feats anyway. Same way, write Extra Spell Known 1st lvl x 3, 2nd lvl x 2) etc.
Of course, in some cases it does require a certain knowledge of prereq feats, but IMO since you don't use those feats anyway, I think the problem will be small.
