Sorry, but it seems you are hinging this connection / similarity argument on baptism for those entering the group, and restoration to eternal life. I don't think you are going to be able to make a very strong correlation here.
Another criticism, along with the fact that mystery religions where not really found in Palestine at the time, is that there is a tendency among supporters of mysticism to collectionize the mystery religions and make them one. And then compare any point that is similar to Christianity.
I am guessing this is much like a number of arguments for evolution, where if you squint just right, these things look similar enough, and then you only look at what fits, and deny what does not.
A far simpler explanation and one that actually matches history, is that Christianity came out of and is based on Judaism.
