Actually, I think that there are any number of women who would be happy to serve in the way Dan describes. There certain is no shortage of men who aspire to be Bishop, for a variety of reasons (e.g., power, status, opportunity to serve, personal growth, etc.). Are women that much different in this regard?
I don't know what your experience in the Church is, but mine is that the people who aspire to callings are normally the ones talented at making Church unbearable. People called as bishops are either:
1 - aspiring for authority, power or looking to satisfy their ego.
2 - men who accept any calling, pull up their socks and do it well (whether it be boy scout leader, primary teacher, stake president or bishop).
3 - scared to death and completely unsure of themselves, but who are willing to try.
If a woman accepted a calling with the attitude of 2 or 3 it would serve the membership well.
It makes sense that women who'd fall in the first category would be the ones who would aspire to the priesthood because the people (male and female) who fall under 2 and 3 are generally happy to use their talents doing whatever they are assigned. I say this with no basis besides my own logic, so it could be completely wrong :P
And for the sake of your perspective Harmony, I encourage you to ask some 12 year old boys and males of any age in the church about how they regard women. Either the majority of the males I know need their perspectives fixed to math yours (myself included) or you need to correct some of your ideas.
