Electrical grounding question

They're still in but I have six 90s total in the run. I cut into the conduit to bypass two of the 90s at my house and I'd need to cut into it to bypass the two or three 90s at the barn to even have a chance of pulling anything through there. Even a new pull string.
Yikes. Are some of them exposed so you could replace them with a "pull" 90? (The ones with the removable plate)
