I was wondering if anybody has ever try this combo before.

I am not considering a full dose of ayahuasca, obviously , more like using a small dose of ayahuasca to make the DMT last longer, as you would with caapi tea, which I have try before.

I have a small amount of aya I got from a reliable source when I was in the jungle, I have taken it solo a couple of times now, I know 20-24 gr of this particular one is a small dose, I was considering taking 5gr one hour prior the DMT, actually, I was planning on taking some changa joints x10 I had, though I guess I could vaporize some spice too.

• What do you think about it?
• Has anyone ever tried this before?
• What would be a sensible dosage of aya?
• Would the spirit of the plant get angry about combining this two?

I don't think you can expect any negative reaction, like angry plant-spirits.
I have never done this, but i have done yopo (bufotenin) on ayahuasca, and that was pretty immersive and powerfull. I guess with DMT the sense of immersion would be even greater.
It would probably result in at least a very intense and interesting experience.
If you realy want to do this, i don't see any reason why you shouldn't.

There are probably some nexians who've already done it. It definately seems like something worth trying. Good luck!
