Viv,

If I understand correctly, you basically have a center tapped (tied to the 
case) neon sign transformer with only one H.V. bushing.  I would get another 
one and connect the primaries in the proper phase to get 10 kv across the two 
H.V. bushings and tie the cases together and to the main RF ground that the 
bottom of the secondary is connected to.
