Yes, of course it's possible.
Sometimes you only need 3-4 voices to get the effect across.
If it were me, I'd just ask some friends, even if you have to do a very primitive recording (not in the studio), just having that real time effect makes more of a difference.
It may sound corny on its own, but in a mix it may work.
Effects that may help afterwards:
Delay
Reverb
Chorus

.. but any of these is vastly improved just by having multiple voices as the source to start with


I do not work here, but the benefits are still awesome
