reversal fogging occurs before the bleach in E-6.
Non-rehal bleach removes silver off the film, rehal bleach rehalogenates it back to silver halide.
C-41 uses a rehalogenating bleach. B&W slides use a non-rehal bleach.
You need a rehal bleach to redevelop.
Rodinal will add a small amount of dye to colour film. There is also no point to the process above. Also the fix needs to be after colour dev, before bleach for re-developing. Otherwise you will just develop fog/flat silver, and will have to bleach and fix the silver off to show your colour image.
You will just bleach back the silver developed b&w neg and re-develop it.. it wont change much, except you'll add a tiny bit more colour through Rodinal.
Normally with re-developing you run C-41 again for more colour/gain.. or b&w dev first to set the tonality from a b&w developer, then fix, bleach, re-develop, bleach, fix, etc.
colour developer (this case C-41) also reduces silver halide to silver, same as a b&w dev, you can dev b&w film with C-41 if you bleach bypass.
What you want to try (from the concept of your idea) is running the C-41 shorter, ie: perhaps 2 minutes, then using a stop bath, rinse twice, and then use Rodinal, and then just fix, no bleach. Or Rodinal first, stop, rinse twice, short C-41, stop and rinse, fix. etc.
That way (either of the last two examples) you can adjust C-41 time for more or less dye as you need it. And adjust Rodinal/b&w dev time/dilution for more or less b&w neg overlay as you need it (ie: if it's overall too dense or too thin).
During my Rodinal re-developing C-41 attempts... 1+100 1 hour stand, and 1+25 (+~16g non-iodised table salt) for 8 minutes both developed C-41 to good density, I redeveloped them to full colour and completely removed the b&w portion of these images though:

Now given C-41 @ 3m 15s @ it's processing temp gives good density for it's process.. it also develops silver, which is removed normally, so bleach bypassing will shoot up the density as you will have dye density + b&w silver density, so C-41 needs to be reduced, as does normal b&w processing time that gives good density for C-41 films.
You may want to drop to 30 celsius, where the full C-41 processing time is arond 8 minutes (according to tetenal), so you can run 3 minutes or 2 minutes if you need to for 1/4 time for very small saturation.
For super low saturation.. you may also be interested in just Rodinal by itself with a bleach bypass.

Exceptionally low.. you could try that... shorten the stand to 30 min, and just add 1-2 min of C-41 @ 30c after that, should give a little more colour. (it was quite dense at the 60 minute stand to begin with)
