Cloaks of Silence

I keep getting hit by inspiration that would be awsome, but non-do-able but this one is, especially as it can be done easily after the models are complete, so... yay!

The plan is to give my entire force green cloaks (greenstuff silly not actually green) i think it'd look awsome on the jetbike riders with the billowing cloaks behind them and heres hoping a hood can hide the horrible jetbikers heads.

Any thoughts on this on greenstuff guides to making cloaks, both would be appreciated
