Who are the members of an early design of Luffy's crew? Browsing through One Piece wiki, there's a databook series called One Piece Green: Secret Pieces. I found a picture of Mugiwara Pirates early design. This is the picture.



I can see Zorro, Luffy, Nami, Sanji, and maybe Usopp, Brook, and Chopper. But who is the other two on the left? Did Robin and Franky replace them? Is there any official information about this picture?
I have no good references but:

The mini character was supposed to be the shipwright and was replaced by Franky.

The other one was meant to be a plant obsessed character who was replaced by Robin and largely incorporated into the post time skip Ussop.
