Can we get that aggro/monster list in PvP?

Can we have this http://i186.photobucket.com/albums/x.../Aggrolist.png in PvP? I think I'd use it very well to stun the Healer when our target is low on HP. Or to get off a DD/Tank to help finish the Healer.

I'd have to ask to have a symbol next to their names too. Their role? But that would make the gate hiding us moot. (If it's intended to hide teams and not show what you're fighting against).

PVPers have been doing that for years. But instead of a aggro list, we use the /focustarget command.

I don't want a single target to have on my screen all the time. I want everyone's HP there because I can't Focus Target multiple people. The point of having this aggro table/Whatever it's actually called, will help me better judge when to stun a Healer or jump on a DD.
