No, Han unification is a completely different thing. Unicode Han unification represents distinct glyphs as the same code point - the intent is that you choose the glyph you want by setting a font (!). This has been acknowledged as a mistake. Having distinct code points for Latin capital letter A, Greek capital letter A, and Cyrillic capital letter A is the reverse, separate code points for glyphs that are identical by definition. That's also a mistake. (Although it might be required by Unicode's other principle of being fully compatible with a wide variety of older encodings. There are many characters, like 囍, that don't qualify to have a code point, but that have one anyway because they're present in an encoding that Unicode commits to represent.)
