Ninja Resurrection is a liberal adaptation of the novel Makai Tensho, written by Futaro Yamada in 1967. In Japan, Ninja Resurrection was actually called Makai Tensho. The protagonist of Makai Tensho is Yagyu Jubei, a very famous samurai that has been used as a hero in many, many fantasy stories over the years.
Given that Jubei Kibagami was created by Yoshiaki Kawajiri as an homage to Yagyu Jubei, it's very dubious to suggest that Ninja Resurrection is any kind of 'successor', spiritual or otherwise, to Ninja Scroll. Especially considering Makai Tensho predates it by many, many years.
It's just another entry in the same subgenre of the medium. If Makai Tensho is inspired by Jubei Ninpucho in any way, it's probably just because the guys that developed it for an OVA (a lot of Mu Animation Studio guys, as I recall) thought it was 'the right time' to work on the project. Sadly, Makai Tensho was never finished as an anime.
If anything, Jubei Ninpucho is a spiritual successor to Makai Tensho.
