Reduce number of font styles on the cover page

The various text styles on the cover page make it look quite busy. It uses 7 different styles:

1. serif, big, bold
2. sans-serif, big
3. sans-serif, small
4. serif, small, bold
5. serif, big
6. serif, small
7. serif, small, cursive

As a reference, here's my bachelor's thesis' cover page:

I actually like the consistent use of sans-serif for titles throughout the document. But maybe we could condense some of the other styles into fewer variants?
