Well, I'm two days late and you've already done it, but what I was going to say was:
Efke 25 is pretty contrasty film and pushing it really hard will make it contrastier* still. Since stand developing is compensating and doesn't really care what EI you exposed at, it seems like it would be a perfect choice.
Since you've already done it and it worked I can pretend to have been really prescient.
*Is contrastier a word? I don't see why it shouldn't be. I'm declaring it a word.
