Yes, it is possible, but hardly user friendly - each user needs to create an AMO account, create a custom addon list and then copy paste id strings back and forth. Only then finaly you can actually use an addon from AMO in your Nigtly Firefox. Frankly sounds much more like jumping through unnecessary hoops than anything. Most users will likely give up than provide much needed feedback to extension authors about how their extensions work on Android.
