[Q]

Atrocities your idea will work and e.g. for the Borg that was exactely what I did in my mod.
However it is quite a bit of work because you must adapt the research and design files for each races not to speak about the designs of the components and tech trees themselves. So if you want to do this for all your races you will be busy for some time!
And for games with human players there has to be a strict code not to cheat by choosing any of these enhanced AI racial technologies.
