Flashing MCU using another MCU

Hello everybody

 I am working on a design using STM8S103F2P6TR and will produce a big quantity of it so I am thinking to make another portable design using STM32F407VGT6 as a flasher to program the units after manufacturing without the need to connect it to a PC which take long time. So is there a way I can store the Hex data for STM8S103F2P6TR  into STM32F407VGT6 embedded flash memory or an external memory associated with STM32F407VGT6 in a portable small design and just connect this flasher device with the main design to program it. As I know STM8/32 MCUs use JTAG for flashing so do I need to implement the circuit for ST-link inside my flasher design or there is an easier way to flash the firmware to STM8S103F2P6TR  with STM32F407VGT6 ?

 

Thanks in advance.
