Especially on cold start up, the steam piping will cause water to drop out of the steam. With the single pipe there is allowance for this water to drain back to the boiler opposite the steam. With your longer piping draining away from the boiler, any significant water will be thrown to the far end, giving water hammer noise. That is why a header and equalizer should be used to dry the steam that is going into the main. Searching this forum page for "equalizer" and "header" will give more. I sent a sketch directly.
