Yes, but it won't be great.
You will see the fireworks from a good spot, but be a bit far back to see all of the effects perfectly. The benches up in front of the railroad station do fill up earlier than most of Main Street.
The problem really is the fireworks run for a while. So you will be going out the DL gates at about 9pm. Then arriveing at Paradise Pier at 9:05. No good viewing will be left in Paradise Park. You may have to watch from behind the park near LM, or the side or back.
It would be much better to watch the WoC at 8pm, from a spot inside Paradise Park against a rail with a Show Pass. This will get you at least one great view of one of the shows. Than you exit as soon as it ends, to get to the front of the departing WoC crowd. Go right to DL and take any spot for the fireworks you see which will probably be around Town Square of the back of Main Street. Try to find a spot that lets you see the Castle and half of the Matterhorn if possible.
