Declaring array of uniquely parameterized classes

In my SystemVerilog environment, I have an array of a class typefor which I need to customize instantiation parameters for each class in the array.  With all classes the same, I can do

 my_class #(.PARAM1(32), .PARAM2(8)) classes[8];

However, I can't figure out how to customize the PARAM1 and PARAM2 parameters for each specialization.  Is this possible?
