There is no such animal.  The modification adapts 3-wire mics (with separate signal and mic powering supply lines) to 2-wire (combined signal and power line).. and reduces sensitivity while raising max SPL handling capability.

You can use an appropriate attenuator to reduce the level of the signal to the devices which follow, but that will not increase the max SPL handling capability of the microphone in the same way.

"Narrow or widely spaced microphone configurations are preferred. It is well-known experience that pure coincidence microphone concepts are not able to produce a satisfying natural spatial impression, due to the lack of adequate interchannel temporal relations (time-of-arrival, phase, correlation)" -G√ľnther Theile
"The mix of the Double M/S signals with a large A/B configuration of omnis results in the spacious sound that is often desired. This option also provides decorrelated low-frequency signals." -Helmut Wittek
