As tempting as it may be, I don't think I would. I am just fine with being the gender that I am, and I am happy to let the others be who they are as well.
The only real temptation to take this imaginary pill would be to see things from the other sides viewpoint; to acquire a higher understanding for the struggles and joys they experience.
In my opinion, God made us just how he likes us to be, straight, gay, trans, bi, boy, girl and everything else. I am certain an entity so powerful as God would require a little variety to stave off the boredom!
