If it turns out the skf bearing is a no-go thats OK. If my analysis of the root cause is good, the pelican bearing shouldbe just fine with a freeze plug behind it to stop grease washout.

The freeze plug & grease washout.I don't understand.
The fundamental problem is that conventional IMSB wisdom suggests the bearing seals deteriorate because of heat.(BTW, the same problem affects a similar bearing in the 6 speed gearbox.) Then the grease washes out because the bearing is partially(1/3) immersed in engine oil.
How will a freeze plug solve the heat deterioration problem for the bearing seals ?
If you fit a Freeze plug and remove one or both seals, that is different.
If you remove both seals ,the logic of a freeze plug is obvious.You avoid partial filling the IMS tube with oil
If you remove just the outer seal, the freeze plug seems unnecessary.
So what does the freeze plug achieve exactly and with which seals remaining/removed?
Assuming it is a good interference fit & doesn't distort the tube during install.
