I can't think of a good reason to re-use old piston rings, other than false economy.
They're relatively inexpensive, consider the damage if they fail.
Only 9 thousand miles...give that some more thought, consider the harsh environment that they operate in, the # of heat cycles that they've endured etc.
It's not a lawn mower, it's a high rpm, precision machine.
Once the rings are compressed, installed, subjected to heat cycles and wear...they are not intended to be re-used again, if they are removed from the bores and allowed to expand again.
Is it worth the risk?
