Combining DES-Amber and prmBSC1 force field parameters

GROMACS version:2020
GROMACS modification: No

Hi all,
We would like to simulate a protein-DNA system using the DES-Amber FF for the protein and the prmBSC1 for the DNA. This is because DES-Amber does not provide DNA parameters.
Does anybody have experience combining these two FF? They are both from the Amber family. prmBSC1 uses a99SB for proteins, and DES-Amber is based on a99SB, so I think they should be compatible, but I would like to see if somebody has already tested them?
