Ask HN: Anyone interested in html to latex style pdf conversion

I am developer for online guilloche vector editor (http://www.torapp.info) and now we have some free time to invest in. I'd like to develope a latex-style layout engine for regular html5 files, so that all html5 files can have a beautiful printout. I'd like to get some advices from you guys since I do not want to develope an application which no one wants. Thanks.
