Before I continue on my Eclipse Phase hack, I actually have to sit down and read the whole game (at least just the core book). I basically needs to know how things work before I tinker with them. Regardless, you could probably do fairly well by my current rules just by adapting/building morphs via Transhuman Tech.
Mostly what I need to know more about is Psychosurgery, Exsurgent Virus and the Mesh, to say the least. Maybe also look at sanity and so on; basically I need to find what systems I need to adapt over.
Also, the tentative title of the hack is Black Stars Rising
