"In 2021, if it doesn't pan out release Gurley then." I think that is highly likely because you can't fix that knee.
but even though I think a upgrade for this broken down version of Gurley is needed to reach that high level of offensive performance, I would prioritize the offensive line first. (I am just saying that the Gurley replacement is the most important piece. Finding that piece a year after next may give you a better chance of finding a better piece)
Fix the offensive line first and get by on fumes this year with Gurley and look for his replacement next year. Goal for next year should be to make the playoffs. Goal for the following year would be the superbowl. Go ahead an start rebuilding the offensive line as it may take a year for that to happen.
