Hey Saswata,
We could not say if it will conflict with anything in your project now or in the future. I could just say that action hooks will simply output what you attach to them.
If you use hooks even our theme’s hooks, you will need to understand how they work so you could say if using them is right for your project or not and you can say if will conflict with anything in your project.
Please note that we do not provide support for custom development even if you use our theme’s hooks because we’d be working on your customizations if we do that and we only offer that service for our Elite customers. If you want us to customize your site, you might want to subscribe to our Elite service here https://theme.co/elite
If subscribing to Elite is not an option, please consider upgrading to Pro and/or kindly wait for our Layout Builder which is coming soon.
Thank you for understanding.
