You cannot change your domestic visa. If your current employer have any business and he employ you there then it's different case & you are lucky. But changing employer/sponsor you should need No Objection Certificate from your current employer/sponsor. Even he give you NOC, you have to employ as domestic worker only with other sponsor. But if you think that you can find another job in company and will cancel your domestic visa after that you will come back with new visa, it's also not possible unless you get NOC from your current sponsor. If you cancel your domestic visa & go back to your home country without NOC, then you cannot come back here again within next 2 years.
