Should we introduce our two children’s birthparents to each other?

We have two adopted children that both came from the same town. In fact, they were born in the same hospital, only 22 months apart. Both sets of birthparents are almost the same age (having no more than 2 years difference between them all). Lately we’ve been thinking about asking them if they would like to meet & get to know eachother. Since their kids are now siblings, we feel they are all not just part of our family, but eachothers as well. We thought it was only natural since they all live in the same area, that they may want to get to know eachother.

Has anybody done this before? Just wondering if it worked out well and what people thought of the idea.
