Moving the DW to the left of the sink will get it out of the prep zone, but keep in mind that the NKBA recommends at least 21" between a DW and a perpendicular counter, because when the DW door is open for unloading, the cabinets in the corner are inaccessible. If you plan to keep dishes in that location, they would first need to be unloaded to the counter, then to the cabinets. The open DW door and the fridge door would also be in conflict, although that's not a big deal to me, and IMO if you have enough space to stand in a corner to unload a DW (at least 15") then the NKBA guideline can be relaxed--but you will have only a few inches.
Adding a prep sink to the island would help with the congestion, but you'd still have zone crossing. However, a helper could load or unload the DW, or gather dishes to set the table, without entering the primary prep zone. (Note that I moved the ovens to the other side of the room, added a drawer MW, omitted the diagonal corner cab, and centered the range/hood between the windows. Window width might need to be adjusted.)
ETA, DW to the right of the sink:
