He also said this regarding Matt's outfit:
If you really want to wear Matt's outfit in SRTT so badly, I'd try porting the outfit you get from doing his side quests in SR4. Idk how to do it (I would like to try to learn how to and port the gat suit from the GAT V DLC eventually for personal purposes ofc
) but I'd try asking VIPER since she is the only person I seen (and remember off the top of my head) who ported clothing (and hair) from SR4.
