I wish I could help... I have the pictures but no longer the websites... The sun/hahns was bought and the owner didn't know what it was until they had done some research and that's the conclusion they came to. Their website is now down and I don't have their contact information.
The other one, what is believed to be a hahns/jenday/nanday hybrid (but I see no jenday characteristics) was found off of hoobly, I believe, and I can't seem to find that either. (actually, doing some looking around, I may have found the person who had/has this particular bird... I'll pm you the e-mail)
I'm interested myself but there really isn't any info out there on conure/macaw hybrids. On Voren's website there is a quote about hahns hybridizing with mitred conures...

The macaws are classified under the name Ara, and these large green conures are, as the name implies, very closely related to the macaws. This relationship has been demonstrated by the fact that hybrid offspring from a cross between a noble macaw and a mitred conure have produced fertile eggs.
