Cuts of that type are made with a shaper using a bit with that profile. It's probably too big to use a router. Shapers of sufficient size to turn a bit of that size are large, powerful machines.

Hand tools and band saw. Cut the tenon with a tenon saw, then cut to cove on the bandsaw. You could cut the tenon on the table saw too, then do the one section on the bandsaw. The shoulders need to be good. The top and bottom of the cove needs to be good. You could scoop out some clearance in the cove with a chisel if needed. You could leave the cove and grab the clearance from the style, if it is easier.
Just a thought
I tried not believing. That did not work, so now I just believe

Cut a mortise on the end for a loose tenon. Then cut the profile with the BS and files and/or sanding drums.. Insert loose tenon. Done.

I'm leaning more toward cutting the slot to match the tenon with either a slot-cutting bit in RT or on the tablesaw w/ a dado blade, and then matching the radius with a round-over bit...
Two pennies worth...
