Hi Chela7:
Sorry, I can't offer much more on combining practices from other systems with AYP. The combinations are endless, and it is really up to the interested practitioner to do their own research.
When considering combining practices from two or more systems, I do offer the general caution to be careful about doing two similar practices in the same session or day, as this can lead to overloads due to a "doubling up" effect.
Reporting back in the forums on such research can be helpful to others considering similar combinations. This is best done in the "Other Systems and Alternate Approaches" forum category. The Deep Meditation/Samyama and Pranayama/Mudras/Bandhas forum categories are for support on the AYP system, not combining with other systems. Things can get muddy in a hurry when trying to mix everything together in one forum category. That may go for the practice routine also.
Btw, there have been discussions in the forums in the past on combining Kriya Yoga with AYP. Try a few searches and you can see what has been said about this before. Or maybe a Kriyban or two will chime in. If so, we prefer that discussion take place in the Other Systems forum category.
All the best!
The guru is in you.
