RBS20 Satellite Unit with RBK352?

I'm certain the answer is going to be no, however I was hoping for a workaround if there is one.

I've got an RBS20 satellite unit from the RBK20 kit (the router died), which I've just replaced with the BGK352 kit.

Is there any way of making the older satellite unit work with the new kit I purchased?

I've tried adding it as a satellite, however that didn't work so was hoping for a work around.

Thanks!
