bigger than a woman. And RJ spent so much time telling us about outliers in these areas ("Taller than most men", or "shorter than his wife", that I find it hard to believe that Balthamel was a diminutive man or that Halima's is particularly tall without us hearing about it. If you assume each body is of "average" size he would have a much smaller body now that he is Halima. In fact he probably lost more size than Lanfear did!

I also think it's clear that as Aran'gar she is no weaker in the Power than before or we would have heard about it just as we did Cyndane. What would be the point of having her be weaker without telling us?
