Is it possible to merge two Whatsapp stories?

Question

Backup

There is an old phone with a history (locally) that no one has been using for a year.
When changing the phone, there was no transfer of chat history.
The new phone has a history within the last year.
Is it possible to combine these stories, including videos?
The option to try and see what happens can end sadly when one of the stories is overwritten. Hence the question.
