Transformers questions by newbies, and not-so-newbies

[CHILENO20]

So G1 Monstructor was made of the 6 inner bots of 6 Pretenders and was very tiny.

If you guys had to design a modern CHUG Monstructor that pays tribute to the Pretender gimmick and the 6 inner bots while allowing the modern combined form to be at least CW 5 piece combiner in height how would pull this off?

Is this a scratch built, pre existing moulds or new moulds question?
