Assuming your diodes are coming from the same mfr lot, (and probably even if
not), just using lots more diodes (rather than R and C) is the preferred
The "equalizing r and c" technique is really a holdover from the days when
semiconductor parameter variations were greater, when diodes were more
expensive than resistors and capacitors, etc.
