I do not believe that it will be economically worthwhile to do this. You may filter the oil but some of the oil molecules has been chemically changed and a filter will not remove them.
Comparing the cost of the damage to your motor to buying new oil I will say buy the oil.

You can't. Some people think that it you let the oil rest for a week that all the grime will solidify at the bottom of the container and the oil is good as new. But that's just B.S. Don't be cheap. You'll screw up your vehicle if you do it enough times.

Only way to re-refine it, is to basically send it back through the refining process (used oil is actually cleaner then what it actually was refined from in the beginning) so its why if you see re-refined oil being sold, its dirt cheap...
theres no way to do it at home......, not only will you have fuel and water condensation that you can't get out at home.... what about the additives in the oil? They wear out and need replacing.... zinc, moly, boron, etc etc.....

The viscosity of the oil is the most important part of oil. the sediment is not what makes you need to change your oil. As the oil is heated, and exposed to slight amounts of water in the fuel, it begins to hydrolyse, and loose its viscosity. This cannot be fixed.
However, used oil can be used in other industry which is why it should be recycled, and not thrown away.
