Many thanks for this!!! Was really helpful.
I ended up unfolding the struct members into an array of member
strings and mapping those to either the struct tuple members or
the struct function members.
This way I can call all members (normal and bitfield members) in
order.

This project is really teaching me some template actions : D.
