There are ordinary chondrites more reduced than the H group. Burnwell is
one. Others were studied by:

Wasson J. T., Rubin A. E., Kallemeyn G. W. (1993) Reduction during
metamorphism of four ordinary chondrites. Geochim. Cosmochim. Acta 57 (8),
1867-1878.

If memory serves, some of the meteorites discussed in this paper were
Suwahib (Buwah), Willaroy, and Cerro los Calvos.

There don't really form an "extension" of H chondrites. They are
anomalous, and have seen different processes.
