Is the Capitol still the top dog for end to end highest percentage of LD passengers ? If that is so then changing it would seem counter productive. As well Capitol was listed as having highest number of passengers connecting <> at CHI ?
According to this post (
http://discuss.amtraktrains.com/index.php?/topic/68624-ld-trains-most-popular-stopscity-pairs/?p=674033), 39% of CL passengers go endpoint to endpoint.
I do think the faster ride is a benefit and potential connections should absolutely be a concern.
OK, let me throw this out there.
The ancient B&O route of the Capitol Limited is slow. Really really slow. It's practically impossible to speed up. And there are so few people along the line, nobody will bother.
Now suppose that serious work is put into upgrading Harrisburg-Pittsburgh. This shortens the time on the Pittsburgh-Harrisburg-Baltimore route.
The Port Road (Harrisburg to Baltimore) can be reupgraded to a reasonable passenger speed at reasonable cost -- though it may be faster to attach an electric locomotive and speed along the Keystone Line and the NEC.
At some point, the ex-PRR route no longer has the 1 1/2 hour penalty over the ex-B&O route.

I don't believe in the "serving small towns" argument as long as we aren't serving large towns. Where's my Ithaca service?
Small towns can punch above their weight, but from looking at the NARP data, generally only by a factor of 2x. (From eyeballing it, college towns can do 3x, though.)
Anyway, there is no virtue in serving Osceola when you could be serving Des Moines instead.
In actual practice, I think small towns are only served because they're on the way -- gotta get across the Appalachians, Great Plains, Rockies somehow.
(I do think the SWC should have been rerouted through Amarillo. It was almost guaranteed to cause a large ridership increase. Instead, taxpayer money was wasted on service to towns which are drying up and blowing away... *and the government doesn't even own the line*, so it's a subsidy to BNSF.)
