2 kitchen sinks+diswasher into 1 drain pipe

Kitchen remodel requires new sink location. Present drain set up has 1 drain pipe through the wall for each sink and the DW stand pipe. 3 in total.

Can I combine the three drains into one of the through the wall drains? If so, do I just cap off the unused through the wall pipes? The three drains now come together in the wall or under the finished floor, cannot see where.

Would it be practical to eleminate the DW stand pipe altogether, and hook the DW drain hose into the fitting on the disposal that is made for this?

lcl242, Welcome to the DIY Forums.
Have to admit, I have never seen a DW standpipe. I would do as you suggested. Combine the drains and since you have a disposal, tie the DW in there. Good luck.
