Combiner articulation question.

Hi guys, there is some amazing work here in these forums.
Hopefully some of you can give me a few suggestions here, but I'm looking to update a custom combiner set I made 5-6 years ago using various special teams members (Motormaster, Dragstrip, Brawl, Air Raid and First Aid) but this time using actual G1-style figures, mainly classics/universe scale.
I have an idea of what I want and how the figures are to be laid out, but I'm getting stumped in the design stage on ways to securely connect them all and to articulate the joints where they all meet, and was wandering if any of you guys would be willing to impart some wisdom on a good way to approach that problem?
Are there suitable connections on other figures that could be copied/used, or would starting from scratch be a better solution?
Thanks in advance for your time.
