I don't know if this was made as a jest or sincerely but it doesn't matter who owns the rights to the Philco name, they would still be considered reproduction cabinets. They are reproductions because they are re-produced, as in produced again. The trademark has nothing to do with it, nor does who is reproducing them, it's the number of years that past since Philco ceased their last production run.
Actually some Philco models did not have cabinets built by Philco, when the production orders exceeded the production capacity of their cabinet shops Philco would contract out to other furniture companies. But even though some cabinets were not made by Philco they are still original cabinets not reproductions. I'm not sure if this happened with the model 70 and 90 cathedrals but it did with with some consoles.
With antique furniture the rule of thumb they use is that up to 25% of a piece can be replaced in repair work and it will still be considered original, more then 25% and it is not. So if you replace the molding, or the front panel with something Steve makes, it's still considered an original cabinet, if Steve builds the whole cabinet it's not, even if he owns the Philco name. If these were terribly valuable sets it would matter, but in this case I don't think it makes much difference. Almost all of his cabinets are going to be replacing originals that were damaged beyond repair.
