I am not sure this is entirely right, I think the main problem is the heat cycles of the air in the IMS tube sucking oil past the seals. I am trying to solve that issue.
So, I am correcting the problem I think to be the root cause of the issue. I can see heat deteriorating the seals to some degree, perhaps a bearing with Viton seals would be ideal. If heat deterioration was the only issue, why would the oil run into the IMS tube, but not come back out?
I am leaning toward the pelican bearing with the freeze plug rather than a fancy ceramic bearing, not sure if I really believe ceramic is needed at this point especially if I change them every time I change the clutch. Standard 6204's are around US $6-10 each. Porsche thought they were a lifetime solution and if I can fix the oil ingress issue, I can probably make 75k miles or so.

P.S. - Here was where I explain my theory
IMS - Going with SKF hybrid
