Re : Would Tikiwiki be sutiable for this...
If really all your pages can do without WikiSyntax parsing, you should find a call to parse_wiki() in tiki-index.php. Something like $data=$tikilib->parse_wiki($info["data"]), just change it to $data=$info["data"].
Another interesting way would be to use ~np~ by default. This tag stops parsing. If you change the line to $data=$tikilib->parse_wiki("~np~" . $info["data"] . "~/np~") to simulate that all your pages start by a non-parsing tag and end by a non-parsing close tag, you could trigger WikiSyntax parsing if you need it by using np in the reverse order : "normal code~/np~WikiSyntax~np~more normal code".
