2 Stores 1 Shopping Cart

We currently have 2 stores and we are thinking of combining them into 1. However, i was wondering if it was possible to keep the 2 stores but have a shared cart between them?

If it is same gateway means, It is possible..

I am afraid, it is not possible out-of-the-box. Additional code modifications will be required
