You are going to need permits. To get the permit you are going to need plans signed by a structural engineer.
Without a permit and approved plans you can do it but the consequences are grave. If you are doing it for somebody else for a fee, you will be involved in a lawsuit later on. If you do it for yourself the subsequent owner will sue you eventually.
There are reasons for plans and permits and you are getting into the area of why.
