Having read your question, here is an example of how I would code it.
-- # The variables for the target file's fully qualified pathname and custom filename needs to be global as they are called from both the handlers and other code.
global theCustomRichTextFilePathname
global customFilename
-- # The createCustomRTFDocument handler contains a custom template for the target RTF document.
on createCustomRTFDocument()
tell current application
set customRTFDocumentTemplate to «data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»

How to create the Custom RTF Document Template, customRTFDocumentTemplate, used in the on createCustomRTFDocument() handler:
In TextEdit create a new Rich Text document and set the font and size as desired, then add any default content, in this case a newline. With this done, press ⌘A to select all, then ⌘C to copy this information to the Clipboard.
Now in Script Editor use the following command to get the RTF class data from the Clipboard.
get the clipboard as «class RTF »
What is returned will be used as the Custom RTF Document Template by assigning it to a variable in the actual script, e.g.:
set customRTFDocumentTemplate to «data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»
Note that the above template has the default font, Helvetica, with size set to 18 and one blank line as its content. If you want a different font then Helvetica, set both the font and size before adding content, a blank line in this case, then use the info above to get is as RTF class data from the Clipboard.
Also note that in the on openDocument() handler, the bounds list is set to {160, 22, 883, 639} not {160, 10, 883, 639} as the second item in the bounds list should not be less then the height of the menu bar.
