ScreenPersonas alternative?

Hi,

Before you shoot this down.

I would love to have screenpersonas available in my company, but we do not have a business case for Netweaver.

Therefore, is there a less powereful but likely equivalent I can use for ECC6 ehp7 without netweaver? (this does mean we can do web services but prefer to keep it in the SAP GUI)

Thanks,

Alex
