Sole-Proprietorship Transfer

I have a sole-proprietorship business under my PAN. I joined a job and they do not allow any other source of income to my PAN. I need to change the PAN of my business without closing the business (or) without changing the GST registration details. Please provide the best solution for this. 1) Can I transfer my sole-proprietorship firm to my mom's pan card/mom's name? 2) Can I add my mom as partner to my existing sole-proprietorship firm and get a new business PAN or use mom's PAN. 3) Will a sole-proprietorship firm under mom's name be automatically transferred to me(only legal-heir) once she dies?
