If by 35 (10%) you mean that 35 is the numerator, this is not such a good idea. That's because it emphasizes something that is not a scientific quantity. A scientific quantity is something that has a meaning outside the current sample. The numerator is dependent on the denominator.
Regarding the other formatting issue, summary.formula with method='reverse' is not flexible enough to allow that.
