Hello Prathamesh,
According to the scenario you mentioned regarding creating tasks and timelines from the previous project and copying them into the new one.
We already have an OOB(Out-of-the-box) feature in which we get a button "Copy Project" on the Project form ribbon.
After clicking this button, each and every project task with the estimation and timeline will be copied to a new project.
Refer to this article link by Microsoft for more information: https://learn.microsoft.com/en-us/dynamics365/project-operations/project-management/copy-project
