You're not going to get a package that will state anything in the following:
2005 1st round pick
2006 1st round pick
Not going to happen (although the Saints accomplished it back when Casserly accepted the deal that made Ricky a Saint and Bailey a Skin)
You're best shot is to say:
2005 1st Round Pick
2005 2nd Round Pick
2005 6th Round Pick
2005 1st Round Pick (Antrel Rolle)
Again, if you have the negotiating power, you're going to get what you want, whether it be Rolle or more picks.
Just a side note, The Texans always have every possible scenario decided out a few days before the draft starts. Straight from one scouts mouth
"We Know every possible trade up, trade down we can make, or who we will get if we stay put"
