There's a simple solution for that: Jolla's AppSupport (https://jolla.com/appsupport/). It enables a Linux device to run Android apps, and it's part of Jolla's Sailfish package.

Someone else already pointed out (https://news.ycombinator.com/item?id=42674279) that HMD and Jolla are both spin-outs from Nokia, so it would seem to be a natural fusion...

Also, it bears repeating: Sailfish is a far better mobile OS than either Android or iOS. It's simple, consistent, and looks great.
