For sure it is possible, but there are many possibilities.
Make a spiral make the same with a different radius, mirror this one and rotate it. Connect ends using Blend Curve
Here a first try.
In order to have some nice transition between the ends I choose the same pitch and an integer number of turns. The idea is to have ends of spirals at opposite.
If you don’t want the same pitch, you’ll have to find a more clever way. But for sure it will be solvable. It is just some Math.
