Triple star source?

My current project is to make 32 RGB spotlights for some Christmas decorations. I have the optics, housing, and driver all sorted and have been using triple XP-E2 stars from ledsupply.com for the first tests. I would like to try some different blue leds as well as possibly lower my cost by buying the leds and stars individually however I have not had good luck finding any that work for me. For my driver I do not have a common anode or cathode so I need to have all six points broken out onto the board. The one I have found is the Noctigon 3XP which while it is very nice, $6 a pop puts it a bit out of my range for this project.

I am not driving the diodes at any crazy current so AL would work fine.

I feel like I am just missing something real easy about these stars that I am not finding them but if anyone could point me in the right direction that would be great.
