No Writing a replacement for the 3DS DSP firmware needs knowledge of the proprietary DSP instruction set and audio hardware, which is not publicly documented.
What it would actually take: The work requires reverse engineering the DSP's ISA and firmware interface through dumping and disassembly, then writing an open firmware that is binary-compatible with what libctru's ndsp expects. It takes specialists in embedded DSP architecture and console hardware, with access to a 3DS for testing.
