This is just an initial proposal for #5804, #5801 and 5852.

I've tested this cases but not had time yet to create an unit test case.
This would make live() able to .live('click otherevent',fn), .live('hover',fn) and also proxys focus and blur events trough focusin and focusout. The problem is that bug #5821 still open, so adding 'hover' would incrase #5821 priority.
I'll look into a testcase later.
Also I'm not sure if I can handle #5821 to provide an stable patch.
