Savage Orc Big Uns, How would you model yours?

SO I have almost finished painting up my first ever block of Savage Orcs and got to thinking. How would I model a unit of Big Un Savages to rival my own 40k Nob conversions? Well I have an idea, quite a neat one, but not one that would make them quite as big as those 40k nobs. However, I am not going to share my idea, not yet at any rate, not until I have made some conversions to wow you with. That is the hope anyway.

So how would you model Savage Orc Big Un's? Do you just use the usual models and say they are savages or have you a dedicated block that you have converted up? Of so feel free to share your idea and pictures here...

I would probably try and green stuff larger muscles and swap in/ only use the bigger weapons! Also adding either plasicard or green stuff under the feet to make them seem a bit taller helps too

I am wondering how many of you would even consider converting up a dedicated savage orc big un unit or just us them as they are?

I would, but then I like to have specific models for almost anything I field. I also really like modelling and converting and I am always looking for good ideas on stuff to convert.

I am currently at the brain-storming point of making a full Savage Orc & Forest Gobbo themed army and so I plan on modelling/painting a unit of big 'uns separate from the normal savage orcs. That said, I have not yet decided upon a good way to make them distinctive. My initial thoughts are to use a combination of fancier warpaint and more bone-talismans & other trophies. Rather than trying to add bigger muscles I was thinking of just making them look meaner and more experienced.

The easiest way would be to use older models as normal boys and the newer range as big'uns.

One problem being that some of the older ones look awful

@Snikpik I am really curious now to know your secret plan!

As for me I can't really think of any method other than what is already suggested.

which metal ones are you refering to?

the ones before these plastics are a bit goofy but the 90's range ones i really like - even tho they are small compared to any orc out now - but i love the old range.

You could also paint them differently, add more fur pelts? I'm out of ideas!

I plan on doing just this, and am thinking about draping furs and hides over them, bit of plasticard under the feet... but I'm not sure what else!

I guess that bulkiing out the regular Savage Orcs' frame with greenstuff and hiding said bulk betneath furs and trophies should work quite well. Maybe looted metal weapons as well?

All of my big'uns have a top knot of bright orange hair, all my normal SOs are bald, having their heads shaved after losing training matches to the big'uns. Only winners are allowed to grow their hair.
