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.
