Dan,
How about two parallel dipoles from the same feedpoint with the 80m  
dipole strung between the 90' supports and about 20' at each end  
hanging down. The 40m dipole could then be 'fanned' downward from the  
feedpoint and tied to the same end support as the 80m dipole.

x               40m dipole attached   x
            at this same feedpoint with
       ends drooping down towards points
    marked 'x' where both dipoles are tied off.
