Hey customizers. I'm not talented in customizing but am custom-curious

I have a short list of figures I've decided Hasbro is never going to make and want to know about customizing them. I've started looking for parts because I don't plan on doing a ton of painting and sculpting. Kitbash is best for me I think.

First up is Yerka Mig. I've seen lots of customs but can't decide what looks most like the worn out spacer. What is your experience with him? I've kinda ruled out Han or Luke because they're a bit too recognizable. I've been trying to find a G.I. Joe or other head. Any suggestions?
