Only if you roughly triple all of the L and C values in the ATU. This
would of course sacrifice tuning performance on the higher bands. A
better alternative would be to either use a longer wire on 80 m, or
insert an inductance in series with the wire. Some experimentation will
be required.
Then there's the T1 :)

For field operations with a KX/40.30.20m, I currently use a 28 feet
random
wire at the end of a 22 feet pole, and an single 16 feet radial on
ground.
The computed impedance is 89 - j 341 ohms at 7 MHz, matched by the
KXAT1.
However, at the low end of 80 m, it should be around 54 - j 1316 ohms,
giving very high SWR. Can the ATU match such values?
