If you hit the 2C really close to the opponent, you can also do this:
2C>6B>3C>2C>tk j.214B>5D>[W]j.236A>j.236B>5C>j.B>j.A>land>5D>[H]2C>6C>5D>[W]5B>JC>j.B>3C>j.A>land>5D>[H]5B>2C>JC>j.B>dj>j.B>j.C(>236236C)
If I remember correctly this does slightly more damage than yours, but it's rather impractical.
Edit: Now that I had the chance to test it, my combo does 5409 damage without the super (60MG) and 6529 with the super (10MG). Also, it seems to work as long as you can connect the 3C>2C at the beginning of the combo.
