I like your thinking – as I also do not only look at their posts or strengths, but also analyse each of their characters. Seeing as you have found also many similarities we could compare them. However, I not only looked for the similarities, but also for their oppositeness as well. If we do that, the line-up can become clearer.
I can distinguish at least 7 BBP, who are – character-wise – the general opposite or have similar traits of their Straw hat counterpart. (Sure, there are character traits which are not reflected in the counterpart of the BBP, but the most prominent of them usually are.) (note: The traits in red do not reflect in the counterpart.)
Now I have the following:
Franky:
- Is “hard boiled” (Dressrosa) – unfazed by anything, though cries if there is a touching story
- Likes to build/invent futuristic tech / is a cyborg
- Extroverted
- Energetic (The Franky arms in the air forming a star)
- Likes to build ships
Juan Wolf:
- Oftentimes tells everyone how much he is uncomfortable and whines about almost everything
- Comes off as someone who seems more than a cave man, with his features (simple)
- Rather shy and introverted (sometimes puts his hand in front of his mouth)
- Comes off as slow
- Is referred to as a ship (battleship)
Zoro
- Fights with swords
- First mate
- Always acts upon honour
- respects other’s honour in general human interaction
- Introverted
- Sleeps a lot
- Doesn’t really say much
- Doesn’t jump headless into fights before he has not evaluated the situation beforehand
- Almost always has a grave expression on his face
- Is distrustful
- If he sees that the general opinion of the crew does sway towards a rather subjective outcome, he puts his foot down and reminds everyone in an objective reasoning of their goals, rules and general unspoken rules (e.g. Beginning at Thriller bark and the incident when Luffy wanted to head after Vivi)
Burgess:
- Fights with bare hands
- Doesn’t care about honour in general
- Likes to use underhanded methods to win
- Sometimes forgets to respect others (calls his commodore “captain”)
- Wears a shopping bag on his head while fighting – doesn’t care how he looks/ disregards the fight
- Calls Luffy a shrimp
- Extroverted
- Likes to yell and mock
- Shows off in the coliseum
- Enjoys the spotlight
- Acts before he has permit by his captain, even if the opponent is stronger than him (as we can see as he is attacking Ace PTS)
- Smiles and grins a lot

Jinbe:

- Can distinguish what is really mattering in a dispute and calms the situation down

- He honours Fisher Tiger’s will, to never kill
Shiriyu

- Is cat-themed with Oda referring to her as the cat-burglar and depicting her multiple times as cat
- Controlls the weather and the air above us

- Loves quiet activities and is rather introverted
- Is reasonable and intelligent
- Tricks or steals from people when she sees an opportunity
- Gets scared easily
- Prefers to be on the safe side
Avalo Pizarro
- As a king, he was once rich and had money in abundance
- Is cat-themed with his laughter (Nyaa-ha-ha-ha), his mane, whisker-like beard and slit-like cat-eyes
- Controls the earth below our feet (Island-island-fruit)
- Doesn’t want to make BB angry
- Extroverted
- Once said that he wants to be the leader (blurts it out without thought), which makes me think that he really isn’t that bright
Ussop:
- Sniper

- Immediately voices his distress to others, when a situation occurs and hesitates when there is danger; everything fazes him, as he often becomes afraid

Chopper
- Doctor
- Wants to heal every illness in the world
- The youngest of the SHP
Doc Q:
- Doctor
- Although he is a doctor, he does not usually cure, but is actually trying to poison everyone
- He is even representing illness with his character as we see him always ill
- Represents also death (coat colour of Stronger is pale, referring to the 4th apocalyptic rider)
- Although he is still in his 20s, he is depicted as rather old looking
Since the 11th SHP is not confirmed, yet, I will remove their counterpart from the list as well. But if you have read my comments on the "nakama thread" you probably know, who I think is joining.
Laffitte:
