This is unlikely for at least two reasons.
First, discharged veterans who had recovered from their wounds and were able to perform military service wrer expected ed to enroll in a regular Confederate command.
Second, citizens taken by Federal troops in hostile action could be executed on the spot as a guerrilla. Federal soldiers didn't take kindly to bushwhackers, and once captured anyone suspected of being a bushwhacker generally experienced a dramatically shortened life span.
There are probably other good reasons as well, but at the moment these are the one that come to mind.
