So, with the recent birth of my daughter I thought now was the ideal time to start yet another new project

I fancied something set in the Mass Effect universe (although whether this will take the form of an RPG using the rather nicely produced d20 rules that can be found floating around the internet or a skirmish level tabletop game remains to be decided) and so picked up a copy of Sedition Wars (lovely models that are a pain to prep by the looks of things) and ordered some bits from Mantic, but I'm a bit stuck on sources for helmets for some Cerberus inspired conversions - can anyone think of anywhere that does helmets that look like this:

Whilst an exact match is unlikely, I'm after something that hits several cues: seperate eyes rather than a single visor, and the bobbly rebreather bits to either side of the mouth ideally!
Having had a mooch around a couple of places, the closest I can see is in a Pig Iron Productions pack, but would mean to get any number of them I'd need to buy several packs that I'd have no use for the majority of

In an ideal world, I'd find a sprue split with similar designs to these:



But I realise that that might be a little unrealistic

I found some helmets by Puppets War that might do for some alien helmets:

But otherwise I'm drawing a bit of a blank!
So, I turn to the combined knowledge of the LAF, has anyone seen something that would suit?
