Nah, I'd want Akainu and Dragon to clash, while the rest of the Revolutionaries escape. So, Dragon wouldn't lose, just get a little banged up and flee once more Mariens show up. I wouldn't mind if Dragon took a small L, though. Aokiji lost to Akainu, and I'm still excited to see what's he capable of now.
Having Akainu scar Dragon somehow would also do a lot to motivate Sabo. Whitebeard DIED during his intro arc, there's no shame in losing to Akainu. Just being able to clash with Akainu for a few minutes proves you're top-tier.
