Mod and EG CV out on Slim Phatty

I am dreaming of CV out for LFO, Arp. and EG from my slim phatty, i got a mp 201 and cp 251 for interfacing it with doepfer modular and metasonix pedals but it would be great that a hardware modification allow me to get cv out straight from the slimphatty.
Am i the only one who want it?
Any way i’ll make it by myself (with a little of reverse engineering…) when the warranty will be expired if no factory mod exist before.
