You could use INSERT in your templates to read in the html. This would
be faster than INCLUDE but only works if you have no TT directives in
the files.

To do the substitution I would use a FILTER on the assembled output.
This is what I'm currently writing to handle the munging of img tags.

I have a wrapper.tt which is processed for every template. It looks
like:

[%- WRAPPER page.tt; PROCESS $template; END %]

I plan to change it to:

[%- FILTER FilterImg; WRAPPER page.tt; PROCESS $template; END; END %]

So that all my img tags get the correct attributes for height and width
and enforce a default alt attribute.

Something similar might work for you.
