No. To generate the analog signal to modulate an FM transmitter for stereo you need at least 53 kHz usable bandwidth with a flat amplitude respnse and perfect linear phase. The minimal practical sample rate would be around 120 kHz. No audio interface I know of, not even those work at 192 kHz, can do this. You'd need an 'instrumentation/laboratory/scientific DA converter for this to work at all.
