Alternative apk for arm v6 devices

For example, you have an AIR app in Google Play, but some unfortunate users are stuck with arm v6 devices. And you want to please them as well.

If I make a light version of the app in native code, can I upload it to Google Play just for the devices that AIR cannot reach ?

Has someone acomplished this yet ?
