Feature Request: i_CTRL-X_iCTRL-P draw from other buffers like i_CTRL-P

I've really come to enjoy the <C-X><C-P> mapping (i've hijacked i_CTRL-J for it). It's more flexible then straight C-P, allowing a form of line completion. But it has one real drawback, it only draws from the current buffer. Is there a fundamental reason it can't draw completion candidates from other open buffers, much like i_CTRL-P does?
Is there a good place to make this suggestion other then here?
Thanks!
