Sooo, i just made a big order on Maya-Ethnobotanicals containing the following
1 x [034-043] 50 g Passiflora incarnata - herb (1) cut
1 x [012-019] 50 g Turnera aphrodisiaca - leaves (1) cut
1 x [170-274] 25 g Heimia salicifolia - leaves (1) shredded
1 x [295-856] 10 g Nymphaea caerulea - flower (3) cut
1 x [128-827] 25 g Justicia pectoralis - leaves and flowers (1)
1 x [042-522] 25 g Peganum harmala - seeds (1) very finely powdered
1 x [013-080] 25 g Calea zacatechichi - leaves and flowers (1) whole
1 x [002-166] 100 g Banisteriopsis caapi - *Yellow* leaves (1) whole
As soon as i get the stuff, i'll try some various combinations of these plants 'n flowers and will report as soon as possible to every kind of mixture.
I've done changa so far only with blue lotus, but it's just not all of it
i think with a mix of these herbs, you can definitly reach a state of ayahuasca by smoking changa 
yeiii, love you all
