Well, it's possible to script folder redirection, but I'm not sure if it's the route you're best going down. Is the Domain which hosts the cluster specific to cluster operation, or have you integrated the cluster into your enterprise Domain? If the latter then redirection of folders may not be your best bet if it is not supported at the enterprise level. If you want to use folder redirection then Group Policy is the way forward.
If you go for the simple network share option then there are several ways to automate mapping of the drive, e.g. net use, powershell, or vbs.
