Advise to a newbee drone pilot using the phantom 4

[Erised]

I am having a great time flying my P4! Very easy to fly and take still photos. Very good flight time from batteries.
The extreme wide angle lens is rather limiting at times.
Has anyone tried to modify the lens with an item such as -

Tele-Photo Flat Zoom Lens Kit For Phantom 3 or 4 - SC-P3416M - Phantom Accessories ????????

I'm not sure how you would mount this lense but I think the weight may be too mutch for the gimbal.
