But Stephen would make such for commercial use within his own lab. I understood the OP's question whether someone would bring anything like Ilfochrome to the market.

This could rather be as special order product for those labs who lately used this material. And actually this was done in a way when Ilford Imaging informed those labs in advance of the planned cancellation of this material. Basically this could be revived for another run. But the company recently decided to cancel all halide activities and released all the related employees. (And meanwhile the rest of the company is gone too.)
This would mean manufacture by another company. None of them showed any interest on this field.
Thus remains a custom production ordered by a meanwhile most probably smaller clientel at much higher prices.

No.
