Definitely possible by hand, have done it myself quite a few times now.
You need a very good iron, a very good light, very good eyesight and a
very steady hand. A stereo microscope is also VERY useful, not required,
but MUCH easier.

There are ZIF sockets out there which convert those tiny packages to
through hole, however they are extremely expensive ($100ish) and I have
no idea where my company gets them.

It doesn't look like that chip comes in a "nicer" package, so I'd
suggest switching to a different chip that's available in a nicer
package, if you aren't willing to go the hand solder route. TTYL
