Is this a good idea?

Hello.
I just aquired a focus 14 blue braille display.
I am an author and used my iPad with a dedicated keyboard. That is currently on repair.
I am thinking of maybe using my braille disllay, connected to my phone, to write my book in Scrivener. I write (ery fast. I have changed a lot of commands to make the thing w*rk the way I want to.
Is this a good idea? Am not going to buy a huge keyboard for the phone.
