just create another snippet to display each form randomly so you can use both 
Or add in SPForm and rotate between three separate contact forms.
Here’s the code (untested) assuming that you have three different contact forms. Just call this snippet on blank page and it will forward to one of the three:
<?php
//Assuming that your three contact pages are 3, 7, and 8
$num = rand(1,3);
switch ($num) {
case 1:
$newPage = 3;
break;
case 2:
$newPage = 7;
break;
case 3:
$newPage = 8;
break;
}
$modx->sendForward ($newPage);
?>
