I'd rather not; there are loads of cool options for incarnum-based homebrew, but I don't really want to get into them. To be honest, low-magic classes like the Psychic Rogue might still work quite nicely even in an Incarnum-based setting, and it's something I might allow if I did this again, but for this I was going for the almost-complete non-existence of psionics and "traditional" magic.
An Incarnum Rogue meanwhile would be very much a homebrew thing, and I'd rather just stay away from that.
Of course, you could just go plain Rogue and take Shape Soulmeld or whatever (Indigo Strike is pretty cool).
