Just after I posted that, I started thinking about it more and decided I wanted to go ahead with it—still a little differently, though. So now I've rearranged the boxes and buried them in the wood chips. The wood chips are now separated from the compost by the boxes, but the boxes aren't as prominent. This way, I can build my garden gradually in small sections and leave plenty of room between my micro-beds (or mini-beds.whichever term sounds better).
