All one dragon is dangerous. Obviously, J10 and L8 are not connected to
each other. Since the connection is so tenuous, I would be tempted to
think the current amalgamation is reasonable.

Have you looked at what moves are tried as attacks and defenses? what
moves are missing from that consideration? Usually these problems arise
from gnugo not seeing the relevant move. After you have identified the
move(s) in question, you can add or modify owl patterns to suggest those
moves.
