Okay, Cap stays, but Steve Rogers's out. There is a reason why he wears a mask. We can always replace the person behind it.
And yet, in all the times that Captain America has been replaced, they've inevitably returned the mantle to Steve Rogers. Why? Quite possibly because it isn't about just the costume, but the man wearing it.

Hopefully, there'll be a new Cap and he will be executed well enough that the character will be popular enough to make the transition. Of course, if that doesn't happen, then Cap will be resussitated and killed off again at some future point, until he gets an heir with traction.
Again, though- in regards to "an heir with traction"- the reason that other Caps haven't taken in the past is because Steve Rogers as Captain America represents something that none of those other characters have. His idealism and conviction- among his other traits- have made him the standout person to wear the mantle time and again. In order to have someone replace him in the hearts and minds of the comic community, you have to craft a character of similar principle and moral character, essentially creating the character you've already got.
I'm not saying it can't be done, and that a writer (with more vision than I have, certainly) couldn't do it, just that it has yet to be done, and that its more difficult than it seems.
You keep pointing to DC, but even their attempts at "Legacy" characters don't always take. Azrael didn't take as Batman, Jason Todd didn't take as Robin, the new Aquaman may or may not take (jury's still out), Kyle Rayner didn't take as Green Lantern- despite what is one of the most directed and long-term attempts to create and support a legacy character. Thus far, Wally West stands out as almost an anomaly in the effort to pass along the mantle, and that was always a rocky road (and there are still people clamoring for a return of Barry Allen to this day).
