Laravel & Symfony hybrid application: need to read laravel routes and use it in symfony

[ruscon]

Main framework: Laravel
Secondary framework: Symfony

Symfony is used to do some work that Laravel can't (there are no ready-made packages for my task)
I found that Laravel can convert it's RouteCollection to Symfony's RouteCollection.
The only one issue is, that need to set the _controller.
Something like this:

    public function toSymfonyRoute()
    {
        $defaults = $this->getOptionalParameterNames();
        
        // May not cover all cases
        if (is_string($this->action['uses'])) {
            $defaults['_controller'] = str_replace('@', '::', $this->action['uses']);
        }

        return new SymfonyRoute(
            preg_replace('/\{(\w+?)\?\}/', '{$1}', $this->uri()), $defaults,
            $this->wheres, ['utf8' => true],
            $this->getDomain() ?: '', [], $this->methods
        );
    }

Are there any contraindications for not doing this in Laravel ?
Is it possible to request such changes in Laravel ?
