I don't understand your question.
Can you post a screenshot of what aggro meter your talking about?
You mean the fervor bars?
If thats what you mean,then there couple things you need to do.
Drop the skin folder called fervor.
Its under my folder on the optionals.
\Optionals\Brygard's\Toolbar Main Bar\Movable mainbar option to use custom fervor\Custom Fervors
Choose the colors you want to use.
Then open up your skin definition file,since you already have the code:
<PanelFile ID="toolbar">
you need to change the width to 417 and hieght to 18.
Like so on the 3 codes below:
<Element ID="GamePlay_FervorPipDisplay" X="303" Y="104" Width="417" Height="18"></Element>
<Element ID="GamePlay_AimPipDisplay" X="303" Y="104" Width="417" Height="18"></Element>
<Element ID="GamePlay_RampagePipDisplay" X="303" Y="104" Width="417" Height="18"></Element>
Also you will need to modified the X and Y to the desire locations.
P.s I dont mind helping.
