You're making it too complicated. It's better to use materials you are highly familiar with.

TMax 400 can be made to look like TXP by underexposing it two stops, shot at 1600. Then you process in something like Xtol 1+1 to regain as much shadow detail as possible, adding about 40% to your normal developing time. This gives you a longer toe, 90% of the shadow detail is still there but is on the toe with less separation (just like TXP), and you bend a slight shoulder for slightly compressed highlights (just like TXP).

Technique is everything.
