If you are set on doing it as a single unit go for total overkill on 
both clearance around the edges and dielectric thickness. I'd still 
be inclined to build at least two and run them in series.
    BTW, I understand that my CP capacitors *are* built using five or 
six separate sections in series (Jim Heagy). Several people who had 
the unfortunate experience of examining the innards of theirs could 
confirm this. Of course there are several ways of skinning a cat.
