Well, virtually everybody who reads these forums is doing this - the generic conversion process from PCM to DSD is that of a sigma-delta (a.k.a. delta-sigma) modulator, and there are very, very few DAC ICs available anymore that don't use this process. And like anything, there are endless variations and methodologies to the process, with myriad pros and cons. See:
http://en.wikipedia.org/wiki/Delta-sigma_modulation
Since virtually all modern ADCs use 1-bit conversion, which is then converted to PCM via sigma-delta modulation . . . the difference between SACD and a PCM format like CD or DVD-Audio is that it's capabable of recording the information before the modulation. (Though I'm skeptical of how often this actually happens in the real-world recording/mastering chain.) Either way, DSD or PCM . . . the information stored is mathematically related, and neither represents fundamentally more or less information than the other . . . just different.
But when you're starting with a PCM source, then converting them to DSD discs . . . all you're doing is choosing a different point in the chain in which to make the conversion process, and the technical difference between doing it this way or simply sticking the CD in your player will be the difference in the way the player's hardware does the conversion process, or the way your computer's software does it. That is, unless one of the two actually does some conversion that you're not aware of (like i.e. the player actually converting all DSD material to PCM for decoding) . . . in which case you're probably going to make things worse.
