I am perfectly willing to be proven wrong but be carefull with the source.
Regulations change and interpretations and rulings change also.
The following would be possible and in agreement with what BigCrecian posted:
Enroll in a course of training for the full FAA PPL certificate.
Meet all the pre solo requirements of 61.87(d), complete the night training requirements and be allowed to fly solo at night under a solo night endorsement.
Big difference here that you are now flying on a FAA Student Pilot Certificate (& medical) and with a solo endorsement.
You are NOT flying on the priviliges of your piggy back 61.75 certificate.
Solo night you would be limited to pattern work as no instructor in their right mind would endorse a student pilot for night cross country.
But that is a sidestep from the original question which dealt with night flying on the 61.75 to which the answer is still NO.
