What team might trade for a Wizards Guard?

The Wizards have one more roster spot and a mid-level exception with which to work, if they so choose. Right now, they look like this:

C: Brendan Haywood, Javale MaGee (Andray Blatche)

PF: Antwan Jamison, Andray Blatche, Dominic McGuire

SF: Caron Butler, Mike Miller (Nick Young)

SG: Randy Foye, Dominic McGuire, Nick Young, DeShawn Stevenson (Mike Miller)

PG: Gilbert Arenas, Javaris Crittendon, Mike James

Right now, the team has too many guards and not enough bigs. If Haywood has another injury, the team would be in real trouble. Are there any teams out there that need an additional roster-quality guard & might have a big they could trade in return?

I'm already aware of most of the free agent options out there. But given the high payroll the Wizards now have, I would be interested to see them trade away someone like Mike James ($6.4 mill. expiring contract) or DeShawn Stevenson ($3.8 mill.) and get a roster-quality big in return. If they could get a starting center and another big, Haywood's $6 mill. contract is expiring as well. In short, I'm curious about trade options more than I am free agents.
