I use1206 parts, they fit fine over the .2in spacing used on our boards

Interesting idea. I wonder (out loud) if changing all bypass caps to something 
like 2012 or larger and mounting them on the back would free up additional 
top-side space in the denser boards? 

I remember long ago that some people used IC sockets with a bypass cap mounted 
in the center of the socket. I think they still make them, but they probably 
cost more than the sum of a regular socket and cap.

For parts ordering, I usually use Digi-Key or Jameco; sometimes Mouser but only 
if the others don’t have it. I also buy odder parts from “acpsurplus” or 
“huskerfan40214” on eBay. I usually buy ahead and in bulk for projects to I try 
to take advantage of volume discounts. The downside is that I have a large box 
of tubes of chips. When a new project comes up, I “go to the parts cage” and 
pull parts, then do a fill-in order if needed. If I’m running low, I’ll order 
in quantity and stock it. For the most part, I’m only doing refill orders at 
this point — it’s rare that I don’t have a part in-stock. I keep an Excel 
spreadsheet of my inventory so I know where I am with stuff.

SMT bypass caps --  a very novel idea ... at least for me.  Need to try it!  
What (physical) size?
