Yup. The example I know of is Dead History by P. Scott Makela. I dont' know if I personally am a fan of the style, but that doesn't mean that you shouldn't pursue it -- I'm sure that other people would have a use for it. As long as you follow through on making the letterforms smoother, I think you should be good to go. Now that I'm looking at yours, the effect is growing on me -- Dead History is a bit too out there for me, but yours has a more pleasing effect, even at this stage. Keep going.
Merely a concept sketch (currently two sliced fonts put together; the final would be a continuous and original whole) ... but what do you think?

Has this been done much before - half one style, half another? If so, can you recommend examples? Is this experimental or just stupid?
