It can be done.
Do you want to invest in the tools required to do this properly without structural or cosmetic damage ?
Along with proper tools you will have to bring some skill which can be learned.
Once you have the tools and pull it off successfully, you will want to scratch build another one.
Then you'll think, crap, I should of just sold off that Sport as is and bought/built new.
If it were me, I'd sell the Sport as is.
