Adapter and app for using 2 sim cards

[pata2000]

Hi

I have a Huawei y6 2017 which has one nano sim.slot. I also use a second mobile equipped with a micro sim.
I'd be looking for an adapter that would allow plugging both sims to the nano slot of my Huawei, and for an app helping me manage both sims.

Is this even feasible?

Thanks a lot!
