Play with the RDX\BlizzFullDisable.lua.

When you modify Line 437-463 like this

--[[
	ChatFrame1:Hide();
	ChatFrame1:SetScript("OnShow", ChatFrame1.Hide);
	ChatFrame1:SetScript("OnUpdate", nil);
	ChatFrame1Tab:Hide();
	ChatFrame1Tab:SetScript("OnShow", ChatFrame1Tab.Hide);
	ChatFrame1:UnregisterAllEvents();
	FriendsMicroButton:Hide();
	FriendsMicroButton:UnregisterAllEvents();
	ChatFrameMenuButton:Hide();
	ChatFrameMenuButton:UnregisterAllEvents();
	ChatFrameMenuButton:SetScript("OnShow", ChatFrameMenuButton.Hide);
	FCF_StartAlertFlash = VFL.Noop;
	
	
	VFLP.RegisterFrame("Blizzard", "GeneralDockManager", GeneralDockManager, true);
	VFLP.RegisterFrame("Blizzard", "ChatFrame1", ChatFrame1, true);
	VFLP.RegisterFrame("Blizzard", "ChatFrame2", ChatFrame2, true);
	VFLP.RegisterFrame("Blizzard", "FriendsMicroButton", FriendsMicroButton, true);
	VFLP.RegisterFrame("Blizzard", "ChatFrameMenuButton", ChatFrameMenuButton, true);
	
	-- combatlogs
	Blizzard_CombatLog_Update_QuickButtons = VFL.Noop;
	CombatLog_OnEvent = VFL.Noop;
	ChatFrame2:Hide();
	ChatFrame2:SetScript("OnShow", ChatFrame2.Hide);
	ChatFrame2Tab:Hide();
	ChatFrame2Tab:SetScript("OnShow", ChatFrame2Tab.Hide);
]]

you should get the Orginal Chatframe Back (Drycoded, not at home yet) If you comment out a Line with -- at line 7-373 the Frame you want should be back.
