You could probably make a larger truss - yes - but a suspension
bridge will always be able to be made longer - and from less LEGO.
The counterweight and bending tower problem is easily fixed at the
same time the span length is increased. ie. take the suspension
bridge with a one meter deck on either end and a five meter deck
between the pillars - 7 meters overall, but with the problems you
described. Now add an extra meter and a half on either end - the
overall span is up to 10 meters, the towers are straight, (because
they're balanced) and no rolls of pennies are needed. ;-)

I would have loved to have seen that in person. Lots of old classic
LEGO and all the added fun and great backdrops of an outdoor layout.
Thanks for sharing the photos.
