In a few new rebuilds I've seen the inclusion of lube slots in the the sun gears.

yes, but does it work, has anybody tried it, it seems it might just weaken the sun gears .

I have never found it necessary to do this. Yes, it can cause a fracture if not done right. From what I have seen, the 4L60E does not suffer from any lubrication problems.
