SugarIcons and FontAwesome in the same definition

Is it possible to have definitions for both SugarIcons and FontAwesome icons at the same time? For example in the menu bar for a module; we would like the sugaricons to appear for newer versions and font awesome to appear for older versions. Can we define in such a way that either will work? We have Module Loadable Packages that need to work with both older and newer versions of Sugar.

        'acl_action' => 'create',
        'acl_module' => $moduleName,
        'icon' => 'fa-plus',
    ),
