The hard part would be to come up with a reasonable replacement for the spars
in the wings. To avoid the big expensive spruce planks, one might have to
consider an engineered product like Laminated Veneer Lumber (LVL)...

Have you ever used those? They are HEAVY, with a capital "H".

I am still very intriqued by filament winding. Spars would probably be
most obvious use of this technology. Take a look at the pictures on
this page to get an idea why.

Doesn't that kindof suggest the ability to make a whole spar, wing,
fueselage or control surface in one shot? I am presuming scaled
composites uses something similar but bigger. I've seen pictures of the
system NASA uses for booster casings, they stand about 20 ft. tall if
I remember correctly.

I will be checking the local yellow pages to see if there are any
mast-makers where I live. I'd like to take a closing look at a system
like this.
