Have you modeled this?  From real world experience with  stacking 
tribanders and monobanders, 3/8 is really too close to get any kind of  pop, 
especially with a long boom.
 
I used a stack of KT36XAs at KH7XS at 92/56/and 29 with a WX0B  box.  The 
XAs are similar to the C31 in boom length.  I found there  wasn't a whole lot 
of gain on the 92/56 on 20, but with all in it was much  better.  The 
spacing was increased from about half a wave length to almost  a full wave 
length.  Triband stacks are always a compromise, and at my new  station the XA 
stack will be at 90/60/30. (back up stack)
