Swapping from Cocoon to Crosswalk after publishing

Besides the difference in bugs that we would have to work around, would this delete a users data? or are there any other problems that we would face? Currently CocoonJS works best for our game with less bugs (no odd volume bug, better performance, few other things) but once crosswalk gets better, we might want to switch to it.

Cannot swap due to the different keystore, Crosswalk auto signs with its key linked to your account.

ok that means we cannot swap after publishing on google play .....

awe man, that sucks. I'd like to wait until crosswalk becomes more stable, but cocoon works best for us right now... thanks for the info!
