Thanks. I should have responded earlier with the solution we went with provided
from a tex stackexchange bloke:
\usepackage{listofitems}
\newlength\maxht
\newlength\maxdp
\newcommand\cbox[1]{%
\readlist*\mylist{#1}%
\maxht=0pt%
\maxdp=0pt%
\foreachitem\z\in\mylist[]{%
\setbox0=\hbox{\z}%
\ifdim\ht0>\maxht\relax\maxht=\ht0\fi%
\ifdim\dp0>\maxdp\relax\maxdp=\dp0\fi%
}%
\foreachitem\z\in\mylist[]{%
\fbox{\z\rule[-\maxdp]{0pt}{\dimexpr\maxdp+\maxht}}%
\kern-\fboxrule%
}%
}
To get a 5--6-tuply nested 0 next to an empty box at each level one would need
only write:\cbox{,\cbox{,\cbox{,\cbox{,\cbox{,\cbox{,0}}}}}} elements of a box
at any level are the comma-separated items.
