Is it possible to create a "fake/virtual" UDI which HAL can manipulate ?

There is no tool to do this (but you can do this IIRC via libhal or via 
FDI-files). The question is: why do you need this? If there is a entry in 
sysfs why not let HAL detect the device instead of add a fake device? What is 
the reason/for what do you need this device/ is there really something in 
sysfs?
