Blueprint vs c++ for mobile apps

Hello everyone
I’v heard that blueprint is 10 times slower than c++ in terms of performance.
I have a question. Is it even possible to make a small app for mobile completely with blueprint or not? (And by a small app I mean something like 2 or 3 character each 4000 tris with 1k textures and say 5000 tris environment and simple ai )

Thanks
