It took a lot of going back and forth, but I have an EZNEC simulation of
a
75/80 m antenna that has an swr below 2.0 from 3.5 to 4.0. If you do put
up
the 4.5 antenna, you can probably use that to extend the bandwidth of the
80
m antenna on the high side.

Could you post what the antenna looks like that will do that bandwidth ?

Easy, two dipoles at right angles. One wire is 133 feet long, the other is
119. The height I used was 75 feet over average ground. I double checked
the SWR. It is below 2:1 from 3.5 to 4.0. If you do it at 75 Ohms, the SWR
is below 1.5:1 from 3.55 to 3.975.
