okay. There was an "Arrancar-Quincy" in that there was an Arrancar who was employed as a Soldat in the Wandenreich and brain-washed (basically) into thinking he was an elite member of Ywhwach's forces... but he was still 100% Arrancar. The only thing "Quincy" that he happened to use was the Bankai Medallion, which was never stated to only be able to work for Quincy. That is to say: We never saw Ebern use anything OTHER than Arrancar abilities.

Ichigo is the only exception in that regard, as somehow he was able to survive infancy despite having Quincy Blood on his mother's side and also the pollution of the Hollow's strain (= Fullbring). Since Ichigo is pretty much not very much well-explained, and since he is the protagonist, I would not reccomend emulating him until it is revealed exactly how it is possible for Ichigo to exist.

Shinigami purify Hollows, Quincy eradicate Hollows. Hollows corrupt Shinigami and poison Quincy. It all works as a cycle. If you plan to break that cycle then you'd need a very good explanation as to 1. why, and 2. how.
