I think it is realistic but to achieve that you'd need to spend a ton of extra money for a out of the box commercial solution. I have the ikea shades as well and it doesn't really bother me too much if they raise at different rates. I set them to open to a specific percentage so they all wind up in the same spot anyways.
I agree, there are some blinds that use different protocols, use different motors etc that should be able to do this but probably at x2-x3 the cost or more.
