Not rocket science to knock something up with the attachment points in the correct place, look at andi06's invisible stations, the attachments are actually a separate im with just the attachments, very easy to make your own attachments, I did for some NG Invisible platforms a while back with Andi's permission, although it wasn't apparently needed! Narrow and low platforms, never got to use them though as my route had several platforms on gradients so you either had passengers sunk into the platform at the uphill end or all leaning if adjusted to the slope!
