im kind of confused with what youre trying to do.
"Can I instead connect the Schoeps capsules, through the KCY and a 5-pin-to-2 XLR’s cable into a phantom power source like the SP DENECKE PS2 with a stereo miniplug output or Sony’s own PCM D1 matching phantom power unit, and from there go unbalanced into mic in of the Sony PCM D1 instead of into the line in like I do with the lemosax?"
if you want to eliminate the sax, you will need either
-a pair of cmc 3,5, or 6 with a phantom power adapter and a balanced>unbalanced adapter cable
-a pair of cmbi mic amps
-an n-box or bill box or one of the other homebrew boxes that replace schoeps bodies
-a pair of cmr bodies and a small battery box
assuming you dont already have mic bodies, the third option is the cheapest, unless you can find a used nbox under $1000
Im pretty sure you are going to need either the sax or the bodies. You need one or the other, but you could go caps>actives>bodies>pre>whatever.
