It is unfortunate. I used to do the same thing with some "simple" commercial epub3s. But to keep both epub2 and epub3 editing possible with the same gui/same tools, sacrifices had to made. Changing the package version "on the fly" was one of those sacrifices.
Luckily, I've found that with those simple epub3s, changing the package version number from "3.0" to "2.0" with an external editor is enough for Sigil to open them as epub2's. Then I can continue downgrading the rest of the stuff as usual. Using 7Zip, I don't even have to manually unzip the archive. I just open the epub in the 7Zip program, edit the opf file, save, close, and re-open in Sigil.
