Thanks guys - I really appreciate the feedback. Sometimes I wonder if I'm doing all the logging for an audience of zero, so it really is appreciated.
With my Martian Goliath power armor ("The Expanse"), I split the morph suit into shirt and pants... adding elastic waist bands to both and few squares of Velcro so the pants overlapped the shirt and they kept each other from separating. I'll do the same with these morph suits. But, another good route that requires no sewing skills is athletic-wear compression clothes. I mean its literally "UnderArmor", right? I noticed this complete set on Amazon that has a compression hoodie and pants. Well... Isn't that just a two-piece morph suit, with a built-in balaclava for the helmet/neck-seal?
