Would it be OK to use the name Thescelosauridae to accommodate not just Thescelosaurus, but also its closest relatives?

Would it be OK to use the name Thescelosauridae to accommodate not just Thescelosaurus, but also its closest relatives? With the recognition of two separate subfamilies within Thescelosauridae (Brown et al. 2013), and the erection of Clypeodonta (Norman 2014) to include all ornithopods more derived than Thescelosaurus (incl. Hypsilophodon), is it necessary to refer to Thescelosaurus as thescelosaurid?
