Yes its possible... You can rightclick on them and use but you cant drop stuff into them as the game will crash.
Right click on the file below and select save as..
Place that file in your custom UI folder
In your custom UI folder find the file called eq2ui_mainhud.xml
Open it with notepad and place this line of code after the last line that starts with <include>
Code:
<include>eq2ui_mainhud_ammo.xml</include>
Save the file
Now ingame either type in or make a macro with this line in it. (case sensitive)
/show_window MainHUD.Inventory
Bingo... place the little window where ever you want it
