First spring repair

Hello, everyone and Merry Christmas to you all. It’s all about Jesus.
Well, this is my first encounter with a broken mainspring. It’s a barrel spring out of a rather odd Bango clock. I have search long to find a similar one but no luck. It’s an Urgos movement but I couldn’t find one like it anywhere.
My question is; If I shorten the spring by about 1 3/4″ or 2″, Is that going to be a problem? It’s the strike side spring. Also, I was wondering if these springs may be set. The barrels are 1 1/2″ Dia. the springs don’t seem to be very large and I’m not sure yet how long this clock will run before winding.
Here are some pics and details. All comments welcome, Thanks, Danny
