Do you mean something like this?

RME has suggested they will work on some tweaks to TM to allow more comprehensive midi control, including the ability to hide unused channels and the ability to control DSP effects. If they do enable such functions, seems like an iPad app similar to AC-7 core could work great. Better yet, I'd love to RME work with an iPad developer to make an app specific for the UFX. Such an app would unlock huge potential to use the UFX as a powerful digital mixer. Not sure how likely that is, but I can hope!
EDIT - while I am dreaming, even better would be the ability to lock two or more iPads running something like AC-7 Core to an individual UFX outputs so one iPad could run the FOH mix, another can run the monitors, musicians can run their own IEM mix etc.
