One Piece Cosplay possbility

I've been trying to decide on which character to cosplay from One Piece, for next year's Sakura Con (and other conventions, if I attend them). I've been batting ideas back and forth, but haven't really finalized on anything.

Then I did a few sketches of a human Thousand Sunny, and Going Merry, and I think the former is a definite possibility (I'm not slight enough to pull off Merry respectfully. Even Sunny'll be a bit of a stretch. c.c; *cough* But anyway...)

Looking for thoughts and opinions on the designs of these! Are they recognizable as the ships they're supposed to represent?
