Sorry but it is not.
Android Studio 2.2 is about to be released and IntelliJ IDEA 2016.2 only supports the plugins from Android 2.0 with caveats.

"The update includes the Android Studio 2.0 features: faster Emulator, experiment GPU Debugger, faster full builds, and code generation and testing for App Indexing. Note, Instant Run is not fully-merged yet."
If you want to drive adoption, it should work on Android Studio as well.
This is what I usually mean by using first party platform languages versus relying on third party support.
For Kotlin, all I need is to install the plugin on Android Studio and am off to the races.
And still I am not using it, because there are a few rough edges with all the Android workflows.
