I'd like to see pictures of that PS bracket as well. Is that an existing setup that you have some run-time with.
I would expect belt slipping and squealing with that setup. The belt contact on the Alt has to be less than 40 degrees of the circumference. The water pump pulley has less than 90 degrees, but it does have two belts. You may want to consider having one belt on the PS pump as it is now. The other, shorter belt around the HB, Alt and water pump would make greater contact on those two pulleys.
With AC I have the Alt belt by itself. The other water pump groove is used by the AC belt. You can see that the PS belt makes insufficient contact on the Alt pulley.

A friend of mine had a long water pump extention and flex fan on his '67. At rpm when the flex fan straightened out, it was out of balance. He let it go and the fan flew out through the hood. Cut through it like butter.
