Homebrew Luma 3DS Input Redirection... through iOS?

[Plasmaster09]

I have an iPhone 6S and a hacked N3DS. Since I know there is (albeit still in beta) an app functioning as a Linux emulator for iOS, there are input redirection programs for Linux and the latest iOS has controller support, I was wondering if these could be combined to result in using my phone as an input redirection device for Luma. As for why... 1) it's not like I can bring my laptop everywhere, 2) I don't have Android and 3) with careful configuration, this could allow for easy multiplayer emulation on one N3DS.
Would this work?

Edit: It seems it would but would be way too slow. However, what I now wonder is: is there an app that allows for something like this without needing a separate tool and OS emulation?
