Looking to create a Real Housewives intro

Hi there!
I'm new here and just got started with Final Cut Pro and I'm loving it compared to Premiere Pro and After Effects. I'm currently working on a fun project for my sisters wedding where she wants to re-create the Real Housewives intro with her and her friends. I have been looking into Apple Motions and I think it should be doable.
How would you do it looking at the clips below? Here is also one fan made from After effects:

... uhm, yezz... doable, yes, beginners task? No.
Basically
* you need your housewives in a green-screen (FCP is very forgiving, for our school projects we used green blankets form the 1$ store and sunlight from a window...)
* key the ladies and apply a nice 'studio' gradient as background
* double those tracks, mask them, de-saturate, keyframe/animate
* apply 'today's episode' edits&cuts.....

a day pre-production, another day in Motion.... if you know what you're doin'.-

Nice idea, btw.-
