Nah..... Quality pres into the 001 is far better than cheaper pres into a 002.
The 002 is only a small improvement in the conversion AND preamp department, and really not worth the upgrade cost.
To go down the convertor path he's be MUCH better off getting an 8ch Mytek or apogee or something like that and keeping the 001.
The PCI 001 also outperforms the firewire 002 in the plugin /track count department.
