Other than changing the code in tree-cfg.c:tree_cfg2vcg(), not really.
Also, this dump is fairly static in that it only happens right after the
CFG is built for the first time (before any optimizations).

Perhaps it would be easier to post-process the dumps that contain basic
block information (-fdump-tree-all-blocks).  I generally use the
attached script to get the CFG out of an arbitrary pass.  It's very
simplistic, but it could be adapted to do what you want.
