Android : Does it make sense to use UE4 for quick-prototyping, Unity3d - for real multiplatform deployment?

I'd like to create an interesting mobile game (I hope it will be really ineresting). There are two best tools on the markeT: UE4 and Unity3d. UE4 has an attractive interface. This interface is very intuitive to understanding. Blueprints are also very intuitive to understanding. But, UE4 is totally not ready for multiplatform's development: Android's support is VERY bad :(

Unity3d is much hard to understand, Unity3d requires much stronger programming's skills, iterface is ugly, not intuitive etc. But Unity3d is really works on almost every mobile platform and for almost every mobile device on the market.

so, does it make sense to "play" with game's prototype in UE4, quickly create and test main logic (Blueprints are great and easy to use), then, after I'll sure my idea is really interesting & attractive for players, move art assets to Unity3d, coding Blueprints's logic in C# etc???
