Base address of SOPC components - exportable?

Yes it should take at least a 32-bit register and an adder. I didn't know you were that low on resources.

The alternative would be a tcl script that reads the .ptf or .sopc file to extract the required base address and write it back in an HDL file. But I don't know if it has been done already, so you may not be able to find any example on how to do that.
