We did some investigation in the past. AFAIK, there are several tools to manage the CP capacity between LPARs that are not in a sysplex: IBMs Group capacity (Free!) and zCost: do not what you look for. BMCs tool iCap (it seems to be called TrueSight Capacity Optimization now) takes the PI's and Importance of workload into consideration, so this is what you are looking for. zDynacap (from SDS?) does the same.
