Router in Miter Stand

I'm putting together the shop in my new house and I was planning to drop my router into the table saw extension as I had done before. However I remember what a pain it was to get everything set up and then have a need to make a quick cut on the table saw. I don't really have room for a dedicated router table, but I'm planning to build a set of cabinets and a large table top for the miter saw and thought what about dropping the router in there?

Has anyone else done this? Just wondering if I'm overlooking any obvious problems. I would be limited to about 4 foot long work pieces. I wouldn't be able to do a dado deeper than about 12 inches from the edge. I think I can live with those two limitations. Anyone else see any gotchas with this setup?

How will you do the fences for each and not limit work?

Whilst perhaps noble and conservative of space, it will have access issues.
A router table, lest a step child, should have access x 360 degrees.
You should be able to work from the backside & either end.
For me? The table has to be mobile or the center of attention.

You might be better off put it in your table saw extension and adding an aftermarket fence. If you can rout in 2 t-tracks 90 degrees to the router you can add the router fence and free up your TS fence.
