Will these wrasses work with my current crew

[spiraling]

Hi all,
my local store has two fairy wrasses and I want to be sure they would be good (peaceful) additions to the tank. Yes I've read @evolved chart many times over

reefer 525xl (approx 100 gal display) (5 feet long)
current:
2 percula clowns
1 royal gramma
1 mccloskers flasher wrasse
1 linespot flasher wrasse

planning
1 exquisite fairy wrasse

the two that are available are
Katherine's fairy wrasse (cirrhilabrus katherinae)
Koi fairy wrasse (cirrhilabrus adornatus)

I would like hardy, peaceful fish
I do QT and have an acclimation box for them.

What is your advise on getting these two?

The Katherine's is fine, but adornatus comes with risk when planning at add the exquisitus later.

thanks, I'll just get the Katherine's tomorrow!
