Would A Mile-Long Condom Hold The Flow?

How hard would it be to make a mylar condom ten feet in diameter and a mile long and to drop the bottom end over the oil leak?

Could we at least relocate the leak to the surface?

Weighted at the bottom, held open by spring wire, the tube could contain the flow, and if it is enlarged at the top, it could also collect the flow as a holding tank.

The flow does not need to randomly disperse into the ocean.

If the tube were twenty feet across, it could hold quite a bit of flow.

What the cost?
