on the c++ side no, they are 2 forked and different code bases in the qt5 
sources.

on the qml language side, i know the differences should be minimal but i think 
there is some detail that has changed in the language/base api

so i don't know how much effort will be to make current qml plasmoids run 
unchanged in qml2, but for a while should be possible to have a plasmoid that 
runs on both, even if will mean for a while conditional  inclusion of files 
with the mechanism for the device specific stuff
