One Piece - Lucci - full body Busoshoky Haki

I was, as always, traveling with my minds and in this case it was about the world of One piece. i was wondering on the different zoan devil fruits and since felins are my favourite animals i was sketching ideas of different types of cats. then i got the ILLUMINATION.

please follow what i'm trying to explain.

Black panthers is not a specific race, they are just some type of leopards that are for some genetic reasons all black (a reverse albinom let's put it on this way).

With this extablish we probabily wont see a zoan devil's fruit model: panther. but i got this incredibly idea!: Lucci! first of all he i an awesome character that i hope will re-appear soon or later and i thought about a freaking awesome power up extremelly legit:
What is Lucci learns haki and use the armanent haki? he litterally become a BLACK PANTHER! that's first of all mindblowning and second amazing. he could start calling his attack like panther kick or shits lke that like every other op. characters and it would be super legit.

What do you guy think about it?
