John, You might have a look at this redbook: http://www.redbooks.ibm.com/abstracts/SG246818.html?Open
It looks at the problem from the other side, i.e. combining disparate systems into a sysplex, but it's still a good read, and a good collection of info from many different products gathered into one place, and should give you some food for thought.
