Future el doesn't have them in stock.
I forgot that they need adapters. Looks like Newark is expecting 3590 ones soon. It's fucked up that one has to order from like 4 different sites. I don't follow the logic of Mouser that they carry a reflector but no adapters and holders for it.
OK, they're not DIY, and they're expensive. Plus nobody seems to want to take my money. However, the Ideal reflector adaptors (RA) and Ledil reflectors (LR) are so cool I want them anyway.
Let's look at the Ideal RA .pdf.
http://www.idealind.com/media/pdfs/products/specsheets/reflector_adaptor_ss.pdf
I can't believe rollitup still hasn't made hyperlinks inside of text more obvious....
According to that .pdf, the Ideal 50-2234C holder accepts the Cree CXA30 series COB's. That includes the CXA3070, which was very popular on this forum a year ago but is now second-hand news.
The second page describes their CXA35 holder, 50-2303CR. According to Ideal, the 50-2303CR will accept the 50-2300AN reflector adaptor. And the 50-2300AN adaptor will accept LEDil Angela/Angelina reflectors.
So, someone correct me if I'm wrong but it looks like the correct picks for the CXA3070 would be: COB holder
50-2234C, then reflector adaptor
50-2100LN or
50-2100AN. The "LN" version accepts the LEDil Lena/Lenina reflectors. The "AN" version accepts the LEDil Angela/Angelina reflectors.
For the CXA35 series COB: COB holder
50-2303CR, then reflector adaptor
50-2300AN.
The part numbers I've bolded above are all Ideal Industries part numbers. All we've done up to this point is spec the right parts that get you to the point of snapping a LEDil reflector into place. Finding someone who will sell you the LEDil reflectors is the next challenge.
Apparently Mouser has some Angelina-W's. $7.78 each - not cheap

And Newark has the right adaptor, 50-2100AN. $.88 each plus whatever ridiculous shipping Newark adds.

So it could be done right now, today, with CXA 30's. If you weren't particular about which Angelina profile you bought.
An Angelina-W is roughly 45 degrees, -M is 28 degrees, and Angelina-S is 17 degrees.
For the CXA35, Newark has some 50-2300AN holders right now.

The 50-2300AN accepts Angela/Angelina reflectors so, again, you could do it today with CXA35. These supplies look to be spotty. And I wish someone carried a wider variety of the LEDil profiles.
EDIT: Someone on another thread mentioned Arrow. I looked. For the CXA30, Arrow has reflector adaptors 50-2100AN and 50-2100LN. They don't stock the 50-2344C holder. For the CXA35, Arrow stocks the 50-2303CR holder right but none are on the shelf (backorder is available) and they don't stock the 50-2300AN adaptor. Arrow has one LEDil reflector, the Angelina-S. I'm guessing that the S might be too much spot for the application...
