Is there a way to redeclare a class in PHP?

Question

I have a main class which is including two other scripts. They both are using a class with the same name which I can't change because it's a library. The two classes with the same name can also have a different Version. When I include the class a second time I get the error that I'm redeclaring the class LicenceManager. My code:
/plugin-one/check_licence.php:

function plugin_one_isLicenceValid() {
    ...
    require "/plugin-one/libs/class.licence_manager.php";
    $licenceManager = new LicenceManager($path, $plugin_name);
    return $licenceManager->isValid();
}

/plugin-two/check_licence.php:

function plugin_two_isLicenceValid() {
    ...
    require "/plugin-two/libs/class.licence_manager.php";
    $licenceManager = new LicenceManager($path, $plugin_name);
    return $licenceManager->isValid();
}

main.php:

require '/plugins/plugin-one/check_licence.php';
$result = plugin_one_isLicenceValid();
...
require '/plugins/plugin-two/check_licence.php';
$result = plugin_two_isLicenceValid();

Is there a way to include the class a second time?

Why its not a duplicate?
Most existing questions seems to be able to edit the including class and add a namespace into it. I can't to that. I can only edit the two check_licence.php files and the main.php
