I'm sad to read this. We talked about those units and structures a few times, maybe some of those were my suggestions I don't remember anymore, and your project kept me interested in working with the hybrid as a race. As a modeler for Revenants I tried to keep our units different from yours in appearance, even though some of them fill similar roles. I thought I'd see both projects released at some point and be able to check their differences and similarities (not exactly compare).
I'm sure mapster community will find use for these and your hybrids will pop around in different projects even if they don't as a unified race.
