I hate to state the obvious, but if you are still trying to have Trisquel
look like it did in the past, it may be best to stick with MATE for this
release and apply the themes from Trisquel 4 or 5. Gnome 3's fallback mode
doesn't come close to the look and features of Gnome 2. That is the sad
reality.
Gnome Fallback isn't that customizable and attempting to hack it is really
wasting everyone's time at this point. The OS is already super late and the
delays are effectively pushing this to a LTS only release as the code base it
is based on will be 2 versions behind by the time Trisquel 6 is ready.
Consort is still very early so that is not an option. Cinnamon is available
for this release, but it doesn't look exactly the same and customizing it
will even add more time to the delays.
Like I said before, use MATE, apply the GTK2 themes, tweak the look where
needed, and call it a day.
