I think you would find it easier (certainly the router would) if you were to drill out the bulk of the waste before routing.

I used a router extension, biggest 'problem' with this is that it takes a lot of shallow passes to get to this depth, haven't timed it but it's probably around 15min to make 1 mortice without squaring the corners by hand, wich takes at least another 10 mins. (at least for me, for a more experienced person it will be a lot faster). As an aftertought, it might be faster by drilling out the bulk with a handheld drill with a depth stop, and then clean it up with a router.
You could always use a kitchen worktop bit, they are not that expensive and are very long, I think the one I have is 50mm long (cutting part), again you have to take very light passes.
