Maybe i'm just yearning after some to play with again? So much sexier than steel.
How about using high tensile steel? It's up to six times stronger than conventional steel.

Sounds like $150 might not buy you the kind of sexy that you want.
Seriously though, more exotic alloys would incur a significant cost increase, at again, little to no performance gain. Aircraft structures often do use steel, but only in places where manufacturing methods or cost prohibit other materials. Having worked in the defense/aerospace industry, I can tell you that those folks work with a budget that normal people like us can't even comprehend.
You should look up a photo of 787 wing deflection testing.
