This isn't specifically to you, but for anyone thinking "Hasbro."
Let's get something straight. Hasbro Jawas, regardless of the amount of rework, will never be good high-end 1/6 figures. They may look "fine" isolated in photographs, but they're never going to come close to these Jawas. If you want something really good, you're looking at making completely custom Jawas from scratch, nothing Hasbro has on their version would be re-usable - for starter's it's all WAY too small.
So, now look at the work/effort of making two completely custom Jawas and you may find your parts list and time are much more valuable than $220. The flip side is that the possibility exists to make a pair even better than the SSC. But it won't be for significantly less than $220 in parts, time and effort - and that's for people who even have the skill to pull it off.
