Nope -- not with the "flex-basis:main-size" proposal, at least (the spec text in the current ED). Part of the point of that proposal is to *change* the meaning of "flex-basis:auto", (to make it mean the same thing as "width:auto" or "height:auto"). So, it's not possible to both implement that new behavior & simultaneously keep the old "auto" keyword behavior as you suggest.
