Pcustom, Pcustom force MOGRAPH

has anyone played around with regions in particles as if they were mograph effectors? they kind of work but there is no fall off and limited nodes which are useful for this kind of work but seems to me a few pCustom and PCustomForce would do the trick. Has anyone already done stuff like this. For example a delay node or offset node for positions rotations and scale. Looks like the variables are available for distance to region but im not much of a coder to pull that off. Maybe some one else already did the hard work lol
