You'd be better served by almost anything else. Either D-76 or ID-11 would be a good place to start. XTOL or Microphen would be even better. Rodinal is nice for some things, but high speed films and Rodinal do not mix well. If it's contrast you're after, don't worry. The ISO speed of TMZ 3200 is naturally around 1000. It is designed as a low contrast medium, so that when you do expose it at ridiculously high exposure indices it will still deliver printable negatives. Expose it at 1000, then process it using the EI 1600 times and the film will deliver reasonably snappy results. If you want more contrast, then just crank up the contrast in the photo editor of your choice, print on a harder grade of paper, or use a harder contrast filter. Capture as much detail as you possibly can on film, and give yourself the option of using it or not at printing time.
