The measurement of diffuse neutrino emission from the Galactic plane provides unique information on the distribution of cosmic rays in our Galaxy. The IceCube collaboration has published a first measurement of this neutrino flux in 2023. IceCube can measure neutrinos through two main experimental signatures: The so called cascades arise from neutral current interactions of all flavors or charged current interactions from electron and tau neutrinos while tracks are produced in charged current interactions from muon neutrinos. The first measurement of the Galactic plane used the cascade channel, but since then hints for the Galactic plane where also found in a track sample. A combined measurement of both detection channels can help to understand the properties of the Galactic diffuse neutrino emission better. Sensitivities and model discrimination power of such a combined measurement are discussed here. *Supported by BMBF and SFB 1491
