Converting Nero TO DiscJuggler?

[vsp]

Yet another stupid question:

I have DJ 4.0 registered, but have not purchased Nero yet. I have a Nero demo version installed, but would prefer to use DJ, as it seems to work better on my system. (That, and it's paid for.)

CDI2NERO converts from CDI to NRG easily enough. Is there a utility that does the opposite, converting NRG to CDI (or a chain of utilities that'll have the same end effect -- say, NRG -> raw files -> ISO -> CDI)?
