Yes it is possible. I'm not feeling like the energizer bunny right now so I will copy and paste from my blog
The Dutch are an interesting military, and this tutorial will work, with a stretch, for Canadian infantry units as well.
The Netherlands, and Canadian army both use the C8 assault rifle, which is a cousin of the M4 carbine/M16 family. This was my first consideration for conversions; the old Caesar US infantry in Desert equipment contains a pile of figures armed with a weapon which I can't identify, but looks strangely like the C8 carbine.
Next, I needed to update the personal hydration system on the figures' backs. I choose the packs from some extra, Caesar Bundeswehr and from a pile of other figs like the Caesar Brits, and some Israeli bits and pieces.
Next I needed to find some helmets, I now realize I could leave the helmets of the original figures on, but in reference pics, the helmet does have a little less definition than the "fritz" helmets on the originals. I choose some extra Israeli heads I had, about two extra British heads and the best ones are from extra French I had.
I removed the SAWs from enough Revell US and glued and plastic-welded them onto various firing figures.
Next up were the HK, AG-36, UGLs. These were simply bits of balsa cut to the appropriate length and CA'ed to the underside of the C8. I used the same method to attach the distinctive "Elcan C-79" sight.
