You can have both.
Install ProfitUI.
Locate the "Inventory" file in your EQ2 Directory within the "UI\ProfitUI" folder. I think name is eq2_inventory_inventory.xml. Rename it, for example to eq2_inventory_inventory.xml.profit.
Download a different inventory which pleases you from here:

Extract the new eq2_inventory_inventory.xml in the ProfitUI Folder.
Done.
This works with most interface pieces
