Forget about it, mate. First two options are simply impossible unless the GEM is similar to that used on hatchbacks. The third option is not that hard, but in order to prevent all indicators lighting up at once, you would have to install 4 separate diodes. It would be too much of a PITA. I explored all these options not a while ago when I was separating the brakes from the indicators on my ZX3.
P.S. I personally think that white rear indicators (although illegal) look rather nice. I mean, they are even less confusing than red turn lights which are often combined with the brake lights. I myself was using the reverse lights as the turn indicators for quite a while and never had any problems with the police. Just my 10 pennies
