I can recommend a company that might help you with that. I had a similar problem before and they were able to fix it. They made the DS conduit fit perfectly. Recently I worked with them again to install
https://tdhomepro.com/. I am happy with how they work. They are quick and efficient and they solve tricky problems like this one with ease. Some of the workers actually helped me with some unrelated garden projects. For example, they helped me with the roof of my orchid growbed. They did all this in their free time of course but for a fee nonetheless. Hope this helps!
