Yes, that would work. It's been done before (Lognkosauria, Turiasauria,
Elasmaria, etc). But we shouldn't have to always tip-toe around
rank-associated suffixes (-oidea, -idae, -inae, -ini) out of fear of future
ICZN entanglements. Euhelopodidae is a perfectly good available name.
Coordinated family-based taxa should be tied to their respective eponymous
genera, not to specific phylogenetic hypotheses. So if _Euhelopus_ gets moved
up the sauropod tree (from outside the Neosauropoda to nested inside
Titanosauriformes) then the Euhelopodidae should follow.
Personally, I'm in favor of abandoning ALL coordinated family-based taxon names
(-oidea, -idae, -inae, -ini), and just adding suffixes that put all
suprageneric taxa out of the reach of the ICZN: Euhelopoda, Brachiosauria,
Mamenchisauria, and so on. Then you can put one clade inside the other (and
vice versa) without raising the ire of "The Code".
