Protonode Lonworks devices simulation

Dear support,
a customer has different Lonworks devices with a specific xif file and progID.
He has also another device with modbus RTU protocol and he would like to integrate it into Lonworks bus, making it acting like a lonworks unit.
I mean: same xif interface file and same progID, in order to let this device appear like lonworks units.
Is it possible with protonode doing such configuration?
I think that setting same progID via configuration file and creating exactly same variables (names and types) it should work, but I would like to know what do you think about that.
