I don't think it would be practical.
Chinese fonts are very large and require many composite glyphs to efficiently reuse glyph outlines. A composite glyph is a letter like à, á, ä, ã or å. The base glyph a is reused multiple times in the same font.
Scanahand cannot create composite glyphs.
It's not difficult to import scanned glyphs into FontCreator. A convenient method is to copy/paste glyphs one at a time from a scanned page of many glyphs. See Scanning an Entire Alphabet
