Low D string gauge for tenor banjo uke

I have a gold tone tenor banjo uke and had put high D nylgut tenor strings on it, but want to try a low D string on it to replace the high D.

There are no string sets for tenor uke for low D and I need to find a string that would work. Any suggestions?

Update: After trying several options, I put on the 4th string of a nylon guitar string of a D'Addario set and seems to work fine.
