The distribution name for LWAMI 4.xx has already been set, Dangerous Water Flight II: ADvanced CAPabilities Modification, or DWF2 or ADCAP or whatever.
The persons involved with the graphics mods are free to name their contribution, but I suggest that anything that utililzes work from SCX at least recognizes the fact that the models were originally distributed as such.
I'm pretty flexible about naming any combined project, but I feel I've been pretty decent about promotion and such. :p
Cheers,
