In the anime Excel Saga they'd have to actually kill off the power leach of an afro director... they she would function far, far better. Luck with that.
If its manga Excel... the real issue is that Excel generates a field or something that makes you think you already told her vital info, and therefore completely ignore ever mentioning it again around Excel. Thus Nick Fury would be requiring repeated trips to the dentist for caps as he keeps finding out that no one bothered to give her the mission briefing... yet again. What she got was vague babble about changing the world and stuff. She'd keep going on missions and somehow completing them despite having little to no idea what just happened. Though it likely includes some random clashing conspiracies and explosions. So she'd actually be a really useful agent... only she'd be happy she completed some vaguely defined goal and the people stuck explaining what just happened would be in for hell.
