Albert,
I do not think the spoke holes or the slots are going to compromise the hub strength in any serious way, as long as the bearing spacing shoulder in the ID goes all the way around the hub.

The main places to be concerned about are those that would see some flexing with each revolution.
The millions of cyclic loading cycles that wheel hubs experience make it imperative that stress does not concentrate too much at any one point. If it does and the flexing amplitude gets too great, then fatigue cracking failure will be inevitable.

This was why I advised eliminating the weight saving sharp corner slot cuts in the bearing spacing shoulder, since they clearly would form a stress riser at the end of the curved slots.
