I'll pass the -10 for synths and -20 as your character is already a bit fucked up by forking (Assuming that's why you took mental illness)
The -30 still remains since its so different from a human body.

If I cound correctly, you roll against 125-30 (75+20+30) so 95, so normal sucess: -10 for a day.

I'll allow resleeving at Von Gogt. No problem with that.
