Hi JT,

I would really try to increase the separation.  The insulation is 
between plates of the cap, not between the outside foil wrap and what 
ever is placed next to the cap body.  You might play games and 
reverse one cap so the two outside wraps are the same potential, but 
there is a limit on how far one can take this.
