EDIT: File updated to v2.0.
I have decided to package and release this as I do have a couple of plans that I intend to try out with it to get a further blend of the two mods (such as restoring the red coloring on the options to close the menus that was seen in DUI) as well as to help promote it further to those who are not so inclined to edit XML files manually. I'll maintain this thread here as a running track of any updates I manage to stammer out with this, and to take potential requests from the community for aspects to try and address that may not have been covered in the original patching process.
Further, please note, all I really did was take some time to figure out what was causing the anomalies that people kept bringing up in the comments for these mods. As can be clearly seen, all that needs to be done is the removal of an unnecessary file that causes some problems if kept in, so all the original work from the original modders is what is present, and thus they deserve the credit for this and not myself. Please ensure to thank these modders for their hard work, and provide their works with endorsemants on the Nexus site so more people can be aware of these great products.
For those looking to mix together the awesome DUIa11+Hotfix by DarN and the great Interface Revelation by SGHi, but have never been able to get the http://fallout3nexus.com/downloads/file.php?id=5054 (not needed) to work with your setup due to the DUI updates that invalidated things, then the solution to your problems is finally here! This fix, to my knowledge, does not work for the Return of the Talking Heads mod (that a patch was also included for by Vomitus originally, and this is because I personally do not use it).
The overall effect is brilliant, in my humble opinion, allowing the HUD, Pip-Boy, and Message Box Interfaces to all have their own unique appearance and feel to them. I would then, personally, recommend combining this effect with the new http://www.fallout3nexus.com/downloads/file.php?id=15771 by Gopher (yep, that's right, this will work just fine with that), and some of the great HUD additions available from there (I myself am using Dynamic Crosshair, Selective Fire, Stimpack Counter, Adjustable HUD or aHUD, and Immersive HUD or iHUD to get a truly modern and unique interface feel to the game).

Install Process and Download Links:
*Note: If you already have DUI and Hotfix/Patches installed, start on Step 2 of the Process
1) Install http://www.gamesas.com/?showtopic=1045221 (and any updates like the http://www.fallout3nexus.com/downloads/file.php?id=2761)
2) Install http://www.fallout3nexus.com/downloads/file.php?id=47 (the textures look just as good to me, and I see no menu lag in my game with it)
3) Install the http://fallout3nexus.com/downloads/file.php?id=15932 (just let it overwrite any files you already have)
4) Load the game and that stuff will be a nice blend without the text anomalies in the Menus.
