It's actually pretty decent for a base to mod indeed.It looks like the same same suit i was looking at on ETSY. They have it on Alibaba and a couple other Chinese websites also. You can buy the complete set or just the jumpsuit. Could probably make a good base with some modding. I would get rid of all the pleather to start
Though I would not recommend removing anything pleather but the shoulder pads , knee pads and the inner elbow piece to replace them with rubber parts or foam.
The reason why is that removing any of the other panels would mean completely disassembly and re assembly would be required at which point making one from scratch would be easier and better (if you had that skill)
For one of these Chinese made things this is actually very decently made and the pattern base is somewhat correct. One really good thing is that it's made from sports fabric (Lycra) and that really helps with heat because this is a HOT costume.
