Welcome here!
I think it can be done, for the company also provides a basic and a mold with the mirrors.
From pic I would say it goes into the fairing as Neil suggests.
First I would mull over the possibility of mirror extenders, mount them and swing the mirrors further forward and outwards.
I did mirror changes on LIKE 200 models (see left blue scoot), where I went on the screen with them, although putting a brace in it for resistance.
