This is the one I'm currently building (with a few modifications):

I think it incorporates most of what you are wanting or, if not, can
spark some ideas about how you might want to do it.

Planning my next router table and thinking about dust collection. My shop
vac works great in my current router table, which is an open stand.

The next router table will have an enclosure for the router, and I want to
add a DC hookup to the bottom of the enclosure to also pick up dust/chips
that come through the bit opening. This made me think of one possible
configuration to use both a shop vac and the DC: Connect the shop vac 2
1/2" hose to the fence dust collection port. Have a 4" Y fitting built in so
that one branch picks up at the bottom of the router enclosure (build
something of a slope into the sides to help funnel chips down to the
opening) and the other branch cobbled into the bottom of the shop vac's bin
to empty it.

My big question is - what would this configuration do to the shop vac? The
normal air flow is coming in the inlet hose, into the bin, through the
filter, and out the outlet vent. With a shop vac connection in the bottom of
the tank, the flow would branch - some going through the filter and out the
outlet, and some going out the DC connection.

Wondering if someone on the wreck has tried something like this. How would
it actually work in practice? Would the DC flow starve the shop vac blower
for air? And if that was the case, would it basically end up being no
different than having the DC connected to the fence pickup through a
reducer? I've read that a shop vac has higher suction, but a DC moves more
air, so it seems that a shop vac would be better suited to pulling chips out
by the fence opening.
