I'm not sure what you are trying to say.

|In the usual twin scenario of SR, neither twin "ages slower"

"Usual" twin scenario is GR scenario for me.

Let amount of time since BB (age of the universe)  is
t0.
We do a common GR twins scenario. One of them
take a rocket, travel, return. Their clocks indicate
t0+t1, t0+t2, t1<>t2.
What is the age of the universe now?
