I found an Elvui edit for WOTLK 3.3.5. The UI is based on the 3.65 version of Elvui for CATA. I uploaded the file here:

Instructions:
This is a modified version of Elv UI 3.65 for Wrath of the Lich King. It's a complete UI makeover, including panels (all panels are themed).
INSTRUCTIONS:
1. Open the Account folder and change ACCOUNTNAME to your account name.
2. Copy Account folder (or just ElvUI files from SavedVariables if you know what you're doing) to your WTF folder.
3. And of course copy ElvUi and ElvUi Config to your AddOns folder.
However, there are a few things to watch out for:
1. Upon opening configuration you will encounter LUA bugs, but upon clicking once again config should open normally. Other that that, there shouldn't be any LUA bugs and everything should work as intended.
2. You can't permanently change the Russian text on Combat Log tab, other than that everything else should be in English.
