Why not simply look at the same sort of strategy that the usraeli-nato-gcc tried in syria ie foment an insurgency as a prelude to a regime change.Even if the regime change part fails to eventuate,the uae would still likely be left in very poor shape economically and its regime would be badly weakened.
A better option for this sort of strategy would likely be in saudi or bahrain,as these have large shiite populations,indeed a shiite majority in bahrain, under the domination of repressive sunni dictatorships.These could be quietly armed and trained with the intention of triggering a large scale insurgency whose ultimate goal would of course be the removal of the saud regime and the breaking up of saudi arabia into 2 new republics.These would be created along sectarian lines ie a shiite republic centered on the persian gulf coast and a sunni republic on the red sea coast.Naturally of course the new shiite arabian republic would be strongly politically aligned with iran.
As for bahrain one possibility would be annexing it back into iran proper,tho ideally this would be done thru something along the lines of a national referendum.
In either case iranian military forces would likely need to be stationed in both countries for the foreseeable future to ensure not only local security and order,but also that there would be little to no successful attempts at regional malign mischief making from the usual culprits.
