This might be terribly memory inefficient, but here's the concept I'd explore (it appears to work on the back of an envelope: your mileage may vary). I know I've done this on smaller cases, but I bet you have a big case so it might not work. It might also work OK in 2D but fall apart in 3D. Slab off all but the overlapping column from the second grid (Slab starts at position 1 in the row dimension). The trick is to linearize the data (or other dependent arrays) for the two grids. This is easy: just Extract them. Then List them one after the other (List is a very cool module that is so simple people overlook its power). Then Construct a new base grid with the correct concatenated dimensions (a few Inquires and Computes to get the numbers you need) and simply feed the List(ed arrays) into the data input of Construct. If necessary, Replace other dependent arrays onto this field with successive serial Replaces.
