Yes! - the 40m yagi at 160 will work VERY well.

>Place the TH7's at 40 and 120 ft.  Use ring rotors or sidearms to

Or better yet - keep looking for more th7's and put one
on top and one at 80' as well.

I will back Tom up on this - I have had the chance to use
ALOT of diffrent height antennas through at least one compleate
solar cycle from the same station.

I would suggest putting up 3 or 4 sloping dipoles for 80 meters.
I have found that they work better on 80m than a rotary dipole at 
150' does for 80m.
