A bump stop such as the one used on AST's (short and quickly progressing to rigid) should be avoided and is as much an indication of appropriate travel. Even with 900# springs (stiffest available in 60mm from swift) in the rear and close to stock ride height there is only about 2.25" before engagement of the bump stop begins. This is very little when considering a loaded suspension that encounters a bump mid corner.
Can you explain what you mean by "cornering power" and how that translates into a bump stop adding mechanical grip and in what situations?
