If I extract samsung clock and weather widget from LP6 stock rom and paste it to system app would it work with CM9 v02? Just curious I really like to have it on my screen
..
There's about 99% chance that none of them will work.
1. stock rom apps are odexed, as opposed to deodexed imilka's
2. they almost certainly need TW framework support, which is not present in CM9
But there's no harm in trying, I suppose. You can always delete them from system/app folder if they fail to perform.
