Should Justice Scalia urge Congress members to work on Booker and ACCA fixes at the inaugural Conservative Constitutional Seminar?

As detailed in this New York Times piece, "United States Supreme Court Justice Antonin Scalia is scheduled to speak Monday on Capitol Hill in a closed-door session with a group of conservative lawmakers that has drawn scrutiny for its ideological tone."  The piece properly notes that it "is not unusual for Supreme Court justices and members of Congress to mingle," and I generally think it is beneficial, not sinister, for judges and justices to speak to legislators about constitutional history and principles.

While various pundits and politicos are complaining about Justice Scalia's willingness to accept an invitation to speak from the Tea Party Caucus, I am hopeful that the Justice will use this opportunity to get legislators to pay more attention to problematic parts of the federal sentencing system.  Justice Scalia has long been a vocal constitutional critic of many parts of the the federal sentencing system (from Mistretta to Almendarez-Torres to Booker), and I hope he helps members of Congress better appreciate jury trial rights and the importance of a constitutionally sound federal sentencing structure. (It would also be great if he would at least briefly channel Justice Alito to explain to federal legislators why the Armed Career Criminal Act is in desparate need of a rewrite.)
