I've ridden to lots of TDs with TD fairings and no indicators/mirrors, without any problem. As most have said, it'd depend who stopped you, but I'd be more worried about the other offences I'd have been committing at the time!
Personally I really like doing it as the bike feels a bit more racey without mirrors (not like they bloody do anything anyway!), and it forces you to use the lifesaver look over the shoulder all the time, which is pretty good practise.
If you don't want to do it just pack a roll of tape and leave everything on.
Cheers,
Ali
