halacha - If a woman proclaims "I am a male", will she become obligated to observe all mitzvos which men are obligated, because of שוייה לנפשה חתיכה דאיסורא?

If a woman proclaims "I am a male, (and I underwent gender-change surgery)", will she become obligated to observe all mitzvos which men are obligated, because of שוייה לנפשה חתיכה דאיסורא - She rendered herself an entity of prohibition?

[Note: If someone finds a source that says that שוייה לנפשה חתיכה דאיסורא only applies to issurim, (prohibitions), then the question can apply to whether she must keep the issurim which men are obligated. ex. not cutting off peyos, not becoming tamei if she's an offspring of a cohen].
