Increase Font size more than 52

Hello, 

We have a lot of courses that use pictures to have more visual options to create tables and organize contents. The problem is, in terms of accessibility, the picture isn't available for screen readers and other accessibility tools. So I'm trying to convert those to tables + images + icon fonts.

I use Icofont as Italic in my font set (like this example), and to resize properly certain icons, I need to go further than the 52px that is in the menu. Is it possible ? Why not adding a custom field where one can just type the size he wants ?

More globally, it would be great to be able to use more than six fonts (body + headers) per course.

Thanks !
