Has anyone ever thought about or tried using a completed IRS & sub-frame assembly from an Infiniti G35? There's a lot of aluminum in those to reduce unsprung weight, and there are getting to be more of them in wrecking yards. LSDs only came standard in Sport models, but are available for the open differentials, though they seem to an atrocious price (e.g. $1400+).
