the topotools supports writing out a "fake" .top file that would allow
building a similarly fake .tpr file sufficient for most analysis tasks
in gromacs.

that would be utterly pointless, since the very basic assumption of a
.tpr file is that bonds and charges don't change (like VMD does, too).
with bond orders you don't really have a simple "is this is a bond?
yes/no" decision anyway. but rather you have a dynamic range.
