There is nothing bad to use another skin than the original.
Indeed I've never kept the original...
You have really plenty of skin to choose from, particularly in BH which has the largest amount of possible choices.
Anyway, if it's only a matter of blurred text rendering, you could try to change the default font used in the original skin, without installing another skin.
Installing and activating a new font only requires a little kwnoledge of Enigma2 architecture and skinning.
