If you say that the transfer is warrented because an SRT rider can get off and transfer to Eglinton LRT, GO, or B-D, then a similar thing should be done with GO. have GO stop at a Kennedy north platform. Riders can either switch to Eglinton LRT or B-D, or have a simple along-platform transfer to the new Kennedy south platform, where they can take the GO into Union. The advantage is that now you can have different headways on Eglinton LRT, Morningside LRT, B-D, GO north (GO train going between Kennedy and Stouffville) and GO south (GO train between Kennedy and Union).
