The only problem is with the duplicates because you can set the wildvalue to be anything. It doesn't have to be numeric. Just avoid/strip out special characters.
The real problem is making sure that duplicates are kept straight between polls without something to uniquely pull the together.
You could consider doing a datasource that counts processes by name. Each name would be an instance and you could count the number of up processes. Set a static threshold when processes that should be multiple are not or set a property detailing how many of the same process should be running and compare that to how many are actually running.
