Simply do not supply the trr and edr to tpbconv.
mdrun does not read the state from the tpr file, but from the checkpoint file
when you give the -cpi option to mdrun.

Yes, but then the tpr file should contain the whole state.
You now never need to create a new tpr file,
unless you want to make the run longer than you orginally thought.
