Makeshift lunar lander using materials from the ET

 Let's assume that you could get the ET to L1.  How can the materials from the tank be used to set up a Moon base?  

Here's the internals of the tank again.  From right working to the left,
there is the liquid oxygen tank,
then the intertank,
followed by the big liquid hydrogen tank.

Let's start with the oxygen tank.  It's the smaller of the two propellant tanks and it looks like a convenient shape.  Could this tank be fashioned into a lander of some sort?


If it were possible, attach legs and rocket engines to the bottom of this tank.  There are some big rocket nozzles at the bottom of the big hydrogen tank.  Detach those and reattach them to the oxygen tank.  Use the intertank as material.  Use the hydrogen tank as a solar furnace, melt down and/or cut the metal needed for the legs and attach it below and/or around the rocket nozzles at the base.

How could that be done?  Make some cable out of the intertank and a harness to tighten up the entire assembly into one tight package.  The harness for the cable would span between the top of the cone of the oxygen tank down to the leg assembly.  At the cone, it would be a circular ring where the cable could fit.  The "leg" assembly could be just the round intertank with spaces cut out of round cylindrical shape of it.  Cut out the middle of the intertank and with all the spaces cut out, you could have room for the rocket nozzles to fit into that space.

There would be enough space between the rocket nozzles and the intertank to give clearance at the lunar surface.  If the nozzles are too big, maybe you could use just one of them.  You would need a way to secure the nozzle to the intertank and that assembly to the oxygen tank with the cable and harness system described. Hook up the rocket nozzle to some smaller fuel tanks that may be fashioned out the remaining material, or brought up from Earth.  

If this contrived contraption worked, it would be left on the lunar surface and serve as the first piece of a lunar base.
