No!!!
And don't forget that there are lots of lightweight 4.7 sailors who get the boat up on their own.
To be honest, I have never put my feet the hull of any boat I have sailed to get it upright.
The trick is just to get as much as your weight on the board as far away from the hull as possible.
If possible, I would practice as follows:
Take the boat somewhere quiet where you can capsize in water just deep enough that you can't stand up - ideally you will be not far off shore, and if possible, you could tether the boat to the shore with a long painter.
Turn the boat into the wind and deliberately capsize it.
Once in the water, swim around to the board - staying below and behind the board facing the front of the boat, reach up and put your hands on the leading edge of the board so that your body is at right angles to the boat.
pull yourself up as much as you can. You do not need to pull yourself right onto the board in a Laser, it will start coming upright long before you get all of your weight on the end of the board.
Once the end of the board starts to come down into the water, start grabbing the gunnels and pull it over that way.
In a real life capsize, it will help if you can let the vang off before you bring the boat upright. This will take a lot of the power out of the sail and reduce the likelihood of a second capsize in strong winds.
It might sound silly, but do you know anyone with a pool in which you can chuck the boat and practice.
