Likely not, seeing as Mayhem and Death Wish add the GenSec elites, which weren't even in PD:TH, and Death Sentence uses the ZEAL team. The models shown are the only ones from PD:TH, and changing the mayhem+ cops to be those models would break the implication in the game that every 2 difficulty levels uses a different police faction (Normal-Hard uses city SWAT, VH to Overkill uses FBI, Mayhem to DW uses GenSec, and DS uses ZEAL).
