Why do you need this application?
If you want to reed news offline using your e-book reader or just from the paper or if you want to create a nice book from several html pages you have to convert your content to some readable and printable format. Most e-book readers supports pdf, and pdf format allows to print the content on the paper easily. Also there are lot's of applications for mobile devices which supports fb2 format. So I do not see any need in supporting any other format.
