Short answer No, especially for what you are trying to do and how you are going about it.
You are trying to load another HTML page contents into RTE in a component.
What you could do to do this:
1. Create a new "HTML Content Load", it should allow a user to select a Path in content tree for the content they want to load and add it to the RTE. This widget should be based on RTE widget but have a new button that would allow loading of content form the repository.
2. Have a good think of what you are doing exactly and what could happen if people can modify source of your pages and if you are still good with that, you can then take inspiration from this AEM Fiddle . Source is available on github.
Have fun!
