This might be a crazy idea. I want to develop a film with both xtol and pyrocat.

I like xtol's capability for the max ISO, also like pyrocat's micro-contrast and smoothy grain effect. If I develop a film, starting with xtol, followed by a thin pyrocat step (before stop bath), will I get both advantage?

If this does not sound that crazy, what would you recommend to split the step?

Totally from a wild guess, I'm thinking this:
1. Run xtol with the develop time for half of the desired ISO (say, 1600 for TMAX 400).
2. followed by a thin pyrocat (1+1+250?), with half the develop time to achieve the labeled ISO (say, ISO 400 for Tmax 400).

Can someone throw in your suggestion to maximize my yield? Thanks.
