The only limit I see is
Quote:
As the soul won't be returning to the original body, only a small portion of the creature's remains are required. These remains must have been part of the original body at the time of death, and the target must have died within the past week.
which gets improved depends the level
Quote:
Heightened (6th) The maximum level of the target increases to 14. The cost is the target's level (minimum 1) × 125 gp. The target must have died within the past month.
Heightened (7th) The maximum level of the target increases to 16. The cost is the target's level (minimum 1) × 200 gp. The target must have died within the past month.
Heightened (8th) The maximum level of the target increases to 18. The cost is the target's level (minimum 1) × 300 gp. The target must have died within the past year.
Heightened (9th) The maximum level of the target increases to 20. The cost is the target's level (minimum 1) × 600 gp. The target must have died within the past decade.
So, since you said the ritual failed but not critically failed, if the time is respected ( which is easy to achieve, because of the Gentle Repose spell ), I say that you can try over and over.
