Usually I'd recommend Nakata -> Kamekun, but there is enough Bogdan, Qubik, Roots etc. to make Nakata a fair choice. Still a change I'd definitely consider. My preference would lean towards Kamekun just for the better overall usefulness.
You might also like to think about Kusuri -> Dao Wang. This is mostly due to the presence of C Wing... I'd rather have a bit of extra power and damage in the same hand as C Wing, as opposed to another pseudo-DR. Also the Freaks bonus makes Kusuri's ability pointless in a lot of situations, and the extra damage might come in handy reaching their minimum.
Nice use of a powerful low * Fang Pi Clang half
If you're worried about SOA dare I suggest Nakata to Muntendon (?) A bit risky but it frees a * and retains a Stop: ability
then one of those 4*s to Naele or Zoid (?)
