It's a tradeoff when you go smaller gauge because the core has to be smaller or the winding even thinner, or both, either of which can lead to an earlier failure, especially if you're bending a lot. (Which is why the G is typically unwound on most electric sets, save the heavier jazz and flatwounds.)
You could always tune down, e.g., to open D, if you're trying for open E, and put a capo on, saving the worry.
