I'm in doubt as to whether the phosphonium ylide attached below is classified as stabilised and therefore should give E-alkene selectivity in a Wittig reaction.

Shades of grey.
My gut feeling would be to the unstabilised side, but I haven't looked it up.

Perhaps putting the cart before the horse but why not try making it and seeing what kind of selectivity you get. May vary with the carbonyl too.
