Serve all assets locally

TLINDEN

Some resources like bootstrap and google fonts are served from external sites. Is it possible to change this so that I serve this stuff myself with local copies (1)?

The reason I'm asking: This is a privacy issue since the original URL is being revealed to those sites via the referrer. My site is completely private and it's not google's or twitter's business, who does what when and how on my forum.

Is that possible? Would be great!

I am aware that I can add custom HTML code and add local references to this stuff, but this does not alter the template which contains the remote reference. And I don't want to modify that template in order to be able to easily update everytime.
