Advance Disable Controller Ui

Not sure if it still works but it was doing that what you ask for: only differently: Use the keyboard UI in gamepad mode. Switch the input mode to gamepad and as you open menus the keyboard UI was shown. Only fight and movement stays in gamepad mode.

Edit:
But as Sharlikran described below keybord and gamepad mode use entirely different variables, controls and technics. And ZOs made "auto detect the input mode by input keys/button press" too. I'm not sure if somehting you ask for would be possible without having to recode ~90% of one of the UI types, which most likely no addon dev will have the time nor the will to do.

Maybe Advance Disable Controller UI still works, check the addon comments. Last time I read them someone said you need to login with the addon, open the inventory twice after another and then it worked (having input mode set fixed to gamepad e.g.).
