Hi,

From your question, I have the feeling that you do not know precisly what a merging procedure is.
Please read those two link:

https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/Matching
https://cp3.irmp.ucl.ac.be/projects/madgraph/wiki/IntroMatching

They will help us to start on this kind of non trivial generation.
You should also check some lecture on the topic to understand what is happening since this is important for the validation of such generation.

Cheers,

Olivier
