Of course I don't know what the business requirements are to make these web enabled. But if the users are looking for excel like look & feel, would it make sense to use different SAS client tools altogether?
My recommendation would be to take a look at Add-in to Microsoft Office instead of WRS, as it allows users to interact with SAS data and use SAS tasks within Pivot or flat tables. Especially if they are already extremely comfortable with that device they can get training on the additional SAS functionality extremely quickly & not loose any functionality that they currently enjoy.
You can also create more 'custom' reports that are run in Add-in to MS Office using the SAS Stored Process functionality. The results are the displayed in the Excel window for the user to interact with in just the fashion you requested.
