I figured you would respond here Reniaa, I forgot to post the one about Michael rebuking Satan.
Regardless of how you look at it, you're simply pointing out similarities. If we can count similarities of Michael and Jesus then conclude them as being the same person, we should be able to do the same with Jesus and Jehovah.
The one trump card that Jesus and Jehovah have is that Jesus says "I and the Father am one"; while no where in the scriptures does Jesus acknowledge such a thing for him and Michael.
I would say it's a circumstantial case for Michael and Jesus, just as it's a circumstantial case for Jesus and Jehovah. You know what the scriptures say regarding drawing conclusions like this "Do not go beyond what is written."
