Publishers and digital storefronts actively monitor for license manipulation.
Keep an eye on third-party authorized key sellers. Wargame titles frequently appear in strategy bundles. You can often get the entire Wargame trilogy (European Escalation, AirLand Battle, Red Dragon) plus all DLC for under $15.
Nothing more is needed. If you do not own the DLC, no safe automated tool can give it to you for free.
