HC-SR04 Ultrasonic sensor without Ultrasonic.h library?

Using Arduino Sensors
4

Hello everybody,
What you think if I connect four PINGs trigger to one arduino pin(for example 12), but four PINGs echo to different arduino pins(for example 6,7,8,9). For what? To save time.. The code should be like this:

int echoPinPingone = 6;
int echoPinPingtwo = 7;
int echoPinPingthree = 8;
int echoPinPingfour = 9;
int trigPin = 12;

void setup() {
  Serial.begin (9600);
  pinMode(trigPin, OUTPUT);
  pinMode(echoPinone, INPUT);
  pinMode(echoPintwo, INPUT);
  pinMode(echoPinthree, INPUT);
  pinMode(echoPinfour, INPUT);
}

What you think will it work correctly?
