Converting "normal" ALV to Web Dynpro ABAP ALV ?

hi,

i have the following customer-requirement:

i have 3 different Z-reports which all have a selection Screen and and Output an ALV Grid List. These 3 reports are called inside NWBC in ESS via SAP GUI HTML.

All sap-Standard application in ESS are in web dynpro ABAP (leave request, travel Management, ...........)

So my customer also wants this 3 Z-reports in web dynpro ABAP. I think i am not the first who needs this, so my question: is there any tool/program etc... which converts "Standard ALV" for the "normal" gui into Web dynro ABAP ?

I don't want to develop the 3 z-reports from ground, so maybe there is a possibility to Kind of "convert" it ?
