I’ve heard of all kinds of string combinations being used on both acoustic and electric instruments. Using a 42 or 46 plain string for the bottom “E” would completely over power the plain 09 or 10 high “E” string. You can find the larger diameter music wire in may hardware stores in spools. You can experiment and when buying a box of 09, 10 or 11 gauge spring steel you can make hundreds of unwound strings. You need to fabricate a way to wrap the ball end around the strings and I solder the wrap so they don’t slip off the ball.

I knew a player back in southern New Jersey who used “A” tenor banjo strings for his D, G, B and high E strings. He had a unique way of playing and a unique sound. His name was Mark Hutchinson and he worked with Joe Seddon in a group called “The Sterling Brothers”. They were one of my early influences when growing up. They played many instrumentals by The Ventures and were fun to watch.
