yes, doing the tank yourself is probably not too hard for you if you've already done the skids and so forth yourself. You'll want a floor jack and a third hand though.
In my case, I drove for about a month with my worst deformation (no photo), until one day it just died on the freeway. That was when the fuel pump tipped over or came loose from its internal mount. My other tanks just gave periodic errors from the fuel sender, showing full tanks when it wasn't. I learned to keep up with the tripometer pretty good. Resetting at every fuel fill. So you can probably live with it. It will help significantly if you tank off the tank skid, pound it flat and reinstall. I'm willing to guess that it will solve most if not all your problems for the short term. That's what I did with my third tank
