Open SAP Logon Dialog external in the NWBC - no link

I like to open a SAP System with the native SAP GUI in the NWBC 6.0

Something like the sapshcut.exe

sapgui.exe /SHORTCUT="–maxgui -sid=XYZ -clt=123 “

or

sapshcut -system=AAE -client=100 –maxgui

Important - It is not possible to use the “sap-nwbc://” link Can someone please help?

Edit:

Some background information:

We are a SAP Partner and we manage several thousand SAP systems. It is not possible to handle this in the SAPUILandscape.xml, so we use an external Program that call/open SAP GUI. Now I like to switch from SAPGUI to SAP Business Client and not every system has a configured NWBC-Service.
