Could you explain what you did?
Hmm, I was not taking notes of all my steps so I am not 100% sure but it should be something like this.
1) Install Vox Populi (No EUI)
2) Delete the "(2) Community Balance Overhaul" folder
3) Delete the following line from "City-State Diplomacy Mod (CSD) for Brave New World (v 27).modinfo" file
<Mod id="8411a7a8-dad3-4622-a18e-fcc18324c799" minversion="0" maxversion="999" title="Community Balance Patch" />
4) Delete the following line from the "(4) C4DF - CBP (v 11).modinfo" file:
<Mod id="8411a7a8-dad3-4622-a18e-fcc18324c799" minversion="0" maxversion="999" title="Community Balance Patch" />
5) Delete the following line from the "More Luxuries (v 155).modinfo" file
<Mod id="8411a7a8-dad3-4622-a18e-fcc18324c799" minversion="0" maxversion="999" title="Community Balance Patch" />
6) Add the following lines in the "CorpText_en_US.xml" file in the "(6b) Community Balance Overhaul - Compatibility Files (No-EUI)\Corporations\Text" folder
<Row Tag="TXT_KEY_OPTIMIZE_SWAP">
<Text>Swap & Optimize</Text>
</Row>
<Row Tag="TXT_KEY_OPTIMIZE_SWAP_TT">
<Text>Rearrange Great Works into potential Themes. Swaps Great Works with other Civilizations and may put excess Great Works up for trade (if needed).</Text>
</Row>
<Row Tag="TXT_KEY_CPO">
<Text>Corporations & Monopolies</Text>
</Row>
7) Delete the following lines from the "(6b) Community Balance Overhaul - Compatibility Files (No-EUI) (v 1).modinfo" file
<Mod id="8411a7a8-dad3-4622-a18e-fcc18324c799" minversion="0" maxversion="999" title="Community Balance Patch" />
<File md5="F4C5FF88A472CDD690729E3FC634634F" import="0">Corporations/Corporations.sql</File>
<File md5="C092419C95C508F846AE763378239142" import="1">LUA/CityBannerManager.lua</File>
<UpdateDatabase>Corporations/Corporations.sql</UpdateDatabase>
<UpdateDatabase>EUI/NeededText.xml</UpdateDatabase>
Note: it seems to work fine but I haven't play a full game yet, I have only tested the very early game.
