Convert module from bulb into remote control

[CableCatDK]

I have a project where I modify a remote control into a wall switch. Right now I harvest the module from a original remote control. But that is both expensive and harder than extraction it from a bulb.

Therefor I would like to reprogram the bulb firmware into a remote control. I have done this over OTA. But the switch only works if the module is directly joined with a bulb. If the module is joined with a gateway, it still appears a bulb.

Therefor I would like to use JTAG to clone a firmware from a remote to a bulb*. But I have zero experience with JTAG. I have borrowed a AVR Dragon, which I don't know how or if it can be used. I consider buying a JLink device.

Which JLink device would you recommend to buy for this purpose?

*There are probably some IDs like ZigBee MAC address that need to be unique.
