UPDATE: I just read a bit about this on Shabbos in Halichos Bas Yisrael. According to that, women are allowed to do all mitzvot except tzitzit and tefillin because those were specifically assigned to men. If you'd like me to post the sources for that, just let me know in the comments!
On a related note, it's very interesting to me that it's normally women wanting to take on the mitzvot of men, rather than the opposite. There are no men running to bake challah or light Shabbat candles. Perhaps this is because men already have more than enough on their plate, while women may feel that their opportunities are limited. My problem is that I'm content with what I have been given, so I lack the perspective to really understand the other side, though I can imagine the frustration.
The lesson? I guess human nature always wants to think someone else is crazier. It helps us feel less crazy :)
