I don't think a walkway between Z and B-Non Schengen is in the current plans, and neither is bi-level gates in B (except for the one they sorta kinda have). Adding this would require completely rebuilding the inner part of B. There were plans to do that complete rebuild years ago, including tearing down the now unused build slicing the B Schengen part in half, but I haven't heard anything about resurrecting it or adding bi-level gates to it. Given that T1 seem in dire need of more Schengen gates I'm also not sure turning B-Schengen into dual Schengen / Non-Schengen gates would buy much. Moving wide body departures off the old part of Z and to T2 would actually help nicely allowing narrow-body turns changing between Schengen and non-Schengen and would reduce the overcrowding there a bit. Maybe that's the plan after T2 reopens?
