Good question.
We cannot say that Sa and Me are Natural Samdharmi (NSD), however they share a special
relationship. Firstly, lets be clear why we say Sa and Ve are NSD.
Saturn and Venus
Taurus and Aquarius are in 4:10 (Kendras) AND Libra and Aquarius are in 5:9 (Trines).
Taurus and Capricorn are in 5:9 (Trines) AND Libra and Capricorn are in 4:10 (Kendras)
So Ve and Sa are considered NSD for each other. Also Ve and Sa are Yogakarak for each other's sign.
Exception is that when Ve and Sa go into 1:7 means they have enimity and they will cease to act as NSD.
So that way, this is considered in KAS.
So for TIMING OF EVENT, if Venus is unable and Sa's antra comes and Ve is powerful for the event, then Sa can step in for it as NSD.
Similarly, if for some reason Sa was unable to give result, and Ve's antra came so Ve will step in for Saturn and will furnish the timing
Saturn and Mercury
Now coming to relationship between Saturn and Mercury and seeing this from KAS view point.
Here they do share a special relationship however its not like Sa and Ve.
From Gemini, Capricorn is 8th house from it. In KAS terminology it's Karak sthan. So if Status of Saturn is good, it means it will give better result or quality of result for Gemini.
This u are already using unknowingly in KAS.
Similarly, Virgo is 8th house from Aquarius, so here Mercury is acting like LoA or Karak for Aquarius. So here better the status of Mercury the better will be the result (quality) of Aquarius.
So Sa and Me are karak sthan for each other's houses so they share a relationship that way.
Saturn denotes brilliance and Mercury denotes intellegence.
However, Saturn can't replace Mercury for timing of event just as Ve can replace Saturn or Saturn can replace Venus.
So Me and Sa do share a relationship albiet its different form Ve and Sa.
