yes, my initial design is a "shoebox" with a flat lid and blue goo.  it was easiest to bolt the carb with bolts from inside the box, so I didn't weld the lid on, but bolted it instead.
while testing my setup without a fuel pump [I have one now] the engine would run only up to about 1300rpm.  I remember I was pumping the throttle to see if that made any difference when I created the "big bang" ☺  now I know why I couldn't get anything out of it afterwards and consequentially gave up for the day.
so, I could rivet some nut plates to the interior and weld it all shut [and not pump the throttle a bunch].  whether a pressure relief valve of some type is necessary would be a topic for discussion.  obviously in flight this would have stopped the engine. [and yes, EFI may have continued to run in this situation]   the shoebox was my crude effort to route two barrels into the four on the renesis.
Ed - are your plastic cast intakes explosion proof?  I certainly understand now why stock intake manifolds always seem so overly strong!
