If the rain had stopped I would call Peter

[EngLearner]

Suppose it's raining. John and Samantha are standing at the window, watching the raindrops falling on the ledge. It seems like it's not going to stop raining soon. John says to her:

1. If the rain had stopped, I would call Peter and Sarah, and we would all go hiking in the forest.

2. If it had stopped raining, I would call Peter and Sarah, and we would all go hiking in the forest.

Are the bolded tenses used correctly in this context? If so, I also wonder if it would be correct to use either "stopped" or "were to stop" instead of "had stopped."

The past tense "stopped", which comes under the second conditional, would be appropriate there, not the past perfect..
