My only empirical experience was with my top guys, which were not resonant 
on 40 but were roughly the same distance from my 40m yagi.  When those guys 
were steel and grounded, the yagi was a dog; when I replaced them with 
Phillystran, the 40m antenna "woke up."  No gross interaction effects were 
visible - no change in VSWR, for example - but something was happening.

I wouldn't chance it.  I'd sooner put up an all-band vertical further away 
from your tower and use that.
