First, go into your EQ files and into the folder marked 'uifiles'. Within that folder should be your 'default' and 'default_old' and whatever custom UI folders you might have created. Create a new folder and call it whatever youd like. Next, go to the 'default' folder and copy the following files into your newly created folder:
gemicons01.tga
EQUI.xml
EQUI_RaidOptionsWindow.xml
EQUI_AdvancedDisplayOptionsWnd.xml
EQUI_GuildManagementWnd.xml
dragitem34.tga
EQLSUI_CreditsWnd.xml
EQUI_AuraWnd.xml
EQUI_BlockedBuffWnd.xml
EQUI_BlockedPetBuffWnd.xml
EQUI_BankWnd.xml
EQUI_BigBankWnd.xml
There is an error in Bank and Bigbank windows that will prevent them from loading correctly you only need to fix 1 line in each file. (should be pretty easy)
XML Files are just normal text files so you can open them in any text editor, i suggest using notepad because some text editors will save extra info that EQ might not like.
once you open the file use the replace feature under the edit menu
Replace
<DrawTemplate>WDT_Filigree</DrawTemplate>
with
<DrawTemplate>WDT_Rounded</DrawTemplate>
and remember, do this for both EQUI_BankWnd.xml and
EQUI_BigBankWnd.xml. Save the changes you make to each xml file and you should be fine.
Next, go to your 'default_old' folder and copy all files in that folder to your new custom folder. If it asks you if you want to replace an existing file, just check off the 'no' box.
Reload EQ, load the skin marked whatever you named the custom folder and viola'! You now have all the bennies of the new UI but the comfortability of use with the old one with all the old icons.
This has worked for me quite nicely. Now, if I can just get Sony to figure out the bug with the NVIDIA graphics cards.....
Mucho Thanks Turlach. 
Thanks Turlach. Using your idea I tried something else too. If you follow your instructions through making the new folder and naming it. Then copy all of the files from the Default folder into the new one. Then go into the Default_Old folder and copy all 3 gemicons files and all 7 Spells files into the new folder and tell it YES you do want to overwrite the files. You get everything of the new ui with spell gem icons from the old ui. They do come out a little smaller though.
This might help for those that just hate the new icons and not the rest of it.
Good luck and again thanks to Turlach.
