Nope. CTE is higher with Glass FRP than with steel.
You would be creating the classic "unbalance" composite.
Also what Milt said.
And I will add that CF is used mostly for its stiffness, not strength. As far as UTS goes, S-glasses are up there with CF and typically provide more toughness than CF. But CF starts out stiffer. To get the same stiffness out of glass, more glass will be used. (more weight)
Fiberglass is fantastic stuff. So is CF. But adding CF to a stiff enough tail is only adding weight, expense, and inviting problems.
