Re-timing a Collision and Technique Advice

[carrrottt09]

I have a tyflow (see attached) that takes a birth shape (a mesh with a few modifiers) that is being collided with by spheres moving out from the center to look like the outer surface is being torn apart from the inside and oozing/ejecting its contents up with a blobmesh.
(I have a blobmesh applied to other spheres that are exiting the mesh surface to represent the insides.)
I've tried retiming this it keeps crashing or giving very different results from the original.

If there are any suggestions on a more efficient way to achieve this, I would appreciate feedback.
