Yes, that combination should work. However, the aug-cc-pVDZ-PP basis set was developed with the stuttgart-koeln_mcdhf_rsc_ecp (a.k.a aug-cc-pVDZ-PP), therefore your basis & ecp output should look like
basis spherical
Mo library aug-cc-pVDZ-PP
N library aug-cc-pVDZ
H library aug-cc-pVDZ
end
ecp
Mo library aug-cc-pVDZ-PP
end
