Dual Kagune are really, really rare, so I think it far fetched no matter what characters are involved.

Besides, I doubt any kagune starts out that well-developed. Most of them probably mature along with the user until they reach somewhere around their mid-teenage years. Touka's single-wing(with a bud of another) was most likely just underdeveloped, perhaps kept at that state through the harmful consumption of human food. We did see her kagune sprouting two wings in the latest chapter, although it looks like she used it in a minimalistic fashion at the time.

Honestly, the merging of two person's kagunes into their child will sound like wishful thinking anytime before Ishida actually reveals it, and personally I think it´d be rather tasteless.
