Dear giovanni,
Thank you for interesting in our EventLight template and submitting the question here. Regarding your question: Yes, it is easy and possible. Joomla allows you to use multiple template on a website. So you can install the EventLight template and assign it only for Events Booking pages / menu items while you can still use your current template for other pages as you want.
If you have any other questions, don't hesitate to let us know.
Sincerely, Giang
