As far as I could see, this is what they look at when upgrading people. An advantage I don't wanna lose obviously. If this is a problem, can I book the tickets with my SEN number and then change it afterwards to another FFP?
Theoretically you can enjoy the status of one FFP while crediting to another. In reality that holds for a few, well defined *A privileges only though, and not all agents can deal with it.
You will definitely sacrifice your mythical op-up priority. You could however wait until the very last second and then switch FFPs right there at the gate, preferably after you received such an elusive op-up.
As for boarding and seat assignment: simply do the former with your SENile card and the latter as a SEN.
