Can amines be synthesized from alkenes via electrophilic addition using ammonium nitrate and ammonia in non-aqueous protic solution?

I've written a mechanism for why I think this may be possible. If I was pressed to decide on a solvent, I'd probably choose ethanol.

Any thoughts?

I think it is not  feasible.
2nd and 3rd steps are possible . but the first step is seems to be impossible(may be possible in very very very drastic conditions) because 

1. NR₃⁺ is not a good leaving group.
2. You are trying to donate electron cloud from an alkene which is a very bad base , or say you are donating electron from a   sp₂ carbon . as you are making a charged specie from a non-polar specie .
