Can I change the font used over a certain character size?

[AC Question]

Hello,

I would like to use a custom font on my Android (Samsung GT-I9195), it is rooted and I have installed cm12.

My favourite typeface (Titillium web) comes in multiple weights (extra-light, light, regular and so on).

The weight that looks good at small size looks very bad, for example, on the big numbers of the clock.

Is there a way to specify a font to be used over a certain size, or at least to choose a different typeface for the clock or other elements?

I haven't heard of any such app. May be it would be available on Play Store.
