Would it take an enormous amount of work to be able to create email newsletters etc using Xara?

I get there are subtle differences in the HTML file, and that different mail clients render HTML differently, but can this be done?

I'm currently using MailStyler, which is supposed to be the 'Rolls Royce' of email HTML editors, but I find it to be quite clunky and buggy.

With a gentle push, surely Xara could do the job?
