Construction is usually described by the materials used, not the age.
Line of sight means you can see the other end. Since you can't see
the other end through 3 floors, you do NOT have line of sight.

I'm also wondering about these 3 floors. Floors are usually 10 to 15
ft seperation. Unless you're shooting at an angle, 100ft would be 8
to 10 floors.

Make my life easy and kindly describe your situation clearly.

If the 3 floors are wood, with not much else in between, you have a
chance. If the 3 floors are concrete, give up now while you're still
sane. Other possibilities will have varying levels of attenuation. In
my experience, 100ft through 3 floors at an angle isn't going to work
because of all the inside junk it has to penetrate. At an angle, it
also has to pass through walls, which often have aluminum foil backed
insulation inside.

At present, I can access the Actiontec's
existing WiFi b/g AP signal with a laptop, getting an adequate signal
and better throughput than the degraded DSL circuit offers.

Ok, no numbers. In order to get 20Mbits/sec thruput, you'll probably
need a 48 or 54Mbits/sec wireless association. That's difficult to do
even in a single room, much less through 3+ floors or walls. Check
your wireless connection (association) speed. I don't think it can be
done.

What I am thinking of is installing a 'wireless bridge' between the FiOS
Actiontec ethernet WAN port and the former DSL network firewall WAN
port, using 600mw WiFi-b/g equipment.

Typical consumer wireless bridges run about 100 mw output. 600mw will
get you perhaps twice the range. For such power to be effective, it
needs to run 600mw at both ends of the wireless line. Otherwise, you
create an "alligator" (an animal with a big mouth and small ears)
which creates more RF pollution.

Is this possible? Is this practical?

I don't think it's possible. You might be able to get a connection at
some really slow speed (i.e. 1Mbit/sec) but not at 48/54Mbits/sec
association.
