Hey Bobby...

what kind of transformer are you planning to use that requires such a high 
voltage level on the caps??

a good rule of thumb for peak voltage level planning is to take the rated 
output value of the transformer and multiply it by 1.4
example..   15KV X 1.4 = 21KV   tack on 10% more and have the cap set rated 
for 23,500 V  this value should be safe enuf for a 15KV trannie...

besides , MMC caps are usually rated for 1500 to 2000 V you would need 
20-40 of them in series PLUS the multiplier to get the farads back up to a 
useable level
very easily talking 100 - 300 caps to reach the levels you are asking 
about...

another option is to use 3 or 4 Maxwell caps rated for 50KV at .1 or so uF 
each  and series them     alot smaller package and more cost effective..
