Canaries with house sparrows

I think it's unlikely that anyone will have my exact situation, but I was wondering if anyone had any experience keeping canaries with house sparrows.

I have two unreleasable house sparrows, both were raised by me as babies and are way too friendly with people (I rescue wildlife), and they live next to my 4 canaries, who have a very large flight cage. I want to move the canaries and sparrows together, as I feel the sparrows might benefit from a larger similar sized "flock".
