If the taxonomy is correct, and if tightly related topics support each other internally, then large link equity is not needed, only strong trusted authority links.

The internal linking on a domain of that size works positively in magnify rankings on its own so long as there are a reasonable number of high level, inbound trusted links to the domain and unique content on most pages.
