If you save the following macro
in the document template (which will thus have to be saved as macro enabled). It will intercept the Paste command in documents created from the template (provided the person opening the document so created still has access to the template). The result will be to match the pasted text to the font at the position the text is inserted. In the case of a rich text content control, the font will be that of the style associated with the control.
