It should. Earlier I downloaded the official 4.2 gapps from goo.im. I took their package and edited it against mine. It has the addon script just like theirs. Only thing I did was update my package against theirs to 4.2.1. Essentially they are identical except mine has the newer JOP40D 4.2.1 google apps from the ota and the gestere keyboard, email and exchange2 apks including wallet. Then I edited the addon script to include those.
