No, the disk inode (/usr/include/ufs/ufs/dinode.h) contains only pointers
to the external attributes block(s).  The primary reason UFS2 dinodes are
larger than UFS1 are the conversion from 32 to 64 bit pointers and a few
extra time structures (e.g. the inode creation time).  If your files are
minimally 1GB in size, I would think you would need UFS2 for the larger
pointers.
