We can achieve this in two steps

Using base controller from Yii1
Using base controller from Yii2

For every step, I have created two repository. We'll use it accordingly

Steps to follow

**: Mandatory

*: Somehow mandatory

(no star): optional

Make your project composer compatible and use yii1 with composer dependency**

Add classmap in autoloader, and put all you resources folder in its value

composer dump-autoload

Resolve all warning for Ambiguous class resolution

Install my both repo using composer**

composer require ahmadasjad/yii1plushyii2
composer require ahmadasjad/yii2plusyii1

Create two branch of git one with yii1Controller and another with yii2Controller
Create a yii2 config directory inside site/protected/config/yii2 *
Copy index.php and Yii2Yii1.php file from ahmadasjad/yii2plusyii1 repo to your site directory or customize index.php according to your files structure and config *
Create a custom Controller and extend it from \ahmadasjad\yii1PlusYii2\Controller **

Now, in every controller extend from your customized controller. This will help you to change only inside your base custom controller in future when you use the controller from Yii2

Replace View class*

Add this to your Yii2 config

'components' => [
    'view' => ['class' => \ahmadasjad\yii1PlusYii2\View::class],
],

Register Yii2 assets in yii1*

Add Yii::$app->getView()->registerYii2Assets(); inside the layout or view file. This will create a bridge in publishing Yii2 assets in yii1.
add return before render('yourView', ['model' => $model]) call inside every controller.
Make your controllers namespaced *: https://www.yiiframework.com/doc/guide/1.1/en/basics.namespace#namespaced-controllers

Add following function inside the config while bootstrapping the app:

function() {
    //Set modelName converter for Yii1 models class in html form
    CHtml::setModelNameConverter(function ($model){
        $className = get_class($model);
        $reflector = new ReflectionClass($className);
        return $reflector->getShortName();
    });
}

Now your config should look like:

return [
    ...,
    'aliases' => [...],
    'bootstrap' => [
        ...,
        function() {
            //Set modelName converter for Yii1 models class in html form
            CHtml::setModelNameConverter(function ($model){
                $className = get_class($model);
                $reflector = new ReflectionClass($className);
                return $reflector->getShortName();
            });
        },
        ...,
    ],
    'components' => [...],
    ...
];

Tips

Remove unnecessary codes generated by GII crud like index.php, _view.php files from view and actionIndex() method from controller
