I hate to be the wet blanket, but the Celtics have virtually nothing to offer another team on draft night to move up.
Our only assets for a trade on draft night are:
Wallace (whose situation is extremely tenuous/murky right now),
Glen Davis (whose BYC status makes any deal complicated),
a core player like Garnett, Rondo, or Perkins,
our own picks this year and in the future,
and/or cash.
