There are many ways as you can imagine,,, for example, XRD can tell you the inter-layer distance (between two adjunct layers) of ur nanopower. And inter-layer distance also effects Raman. So if you vary this distance experimentally (may be by oxidation or reduction) then first you can determine this by XRD and can see the consequent changes in Raman effect as well. In this case, adding oxygen or reducing into the system also change XRD and Raman as well. This is just an example how to plan ur experiment. U can use any other properties as well, such as crystal defects. XRD & Raman both changes due to changes in crystal defect in the Gr powder. Hope this is help u to plan something.. Good luck.. CB...
Please refer to the paper: Facile Synthesis and Characterization of Graphene Nanosheets J. Phys. Chem. C 2008, 112, 8192–8195 . It may help you. Best wishes, DM
As it was suggested by Chandan, there are many ways to relate XRD to Raman. What i have done in my research is that i have noticed that the changes in molecular structure which can be determined by XRD can be related to Raman spectroscopy. For example:
I investigated on Donor/Acceptor BHJ organic solar cells, and noticed that there is an interrelation taking place within my polymer as i am changing the ratio of D-A. this was causing deformation of the thiophene rings in my polymer. this was clearly observed in Raman spectrum as it was showing a shift towards lower wavenumber indicative of the molecule being under stress.
Please see my paper below:

Raman spectra is good technique to study crystal structure, disorder and defects in graphene based materials. The ratio of intensity of D/G bands in Raman spectroscopy is a measure of the defects present on graphene structure.
Amorphous peaks do not have a Miller index because they are not due to a lattice plane of a regular lattice. . Peaks in XRD patterns of small particles of nano-size graphene composites are wide and less intensity. Graphene is nanoparticulate material which not fully crystalline , due to the strong disorder and irregular packing of the layers and randomly arrange of atoms. Raring and weakness of peaks XRD spectra associated with graphene composites ,but XRD pattern may exhibits some distinctive peak of graphene. Peaks position and intensity in XRD and Raman spectroscopy are reflect any structural changes in graphene .
XRD and Ram an spectroscopy techniques are an But each depends on the scientific basis of the technique and if the identify agrees leads to confirm the chemical compositionanalysis methods to identify the structure of the compounds, for more clarification check the link:https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5497829/
