ER Self-initiating model submission

I've been on this forum quite a loooong time. I just never post anything. I'm mostly on CFA forums.

However, I recently got a call from a MD for a ER position. He said he will be away the coming weeks and will reconnect in January. But Im afraid he will forget me by then. I have been on some interviews where they ask for models and write ups. I am thinking of initiating that and do a model and write up for him while he's away. Or would I be kicking myself here? What if he didn't even want one and I screw up the model? Any thoughts? I've never been on a ER interview.
