I suspect those rafters are much stronger than you are giving them credit
for. If they’ll support 3-4 inches of snow they will surely support a 400 lb
casting. Would they support you doing a chin up? How about 2 or 3 men
simultaneously doing chin ups? That’s all the weight you are asking them to
hold up for an average piano.

I don’t know what kind of span you are looking at, but you could probably
throw up some more 2x4s and build some pretty sturdy trusses for well under
$50.

R.C.,
I've used a "cherry picker", (the collapsible type), a couple of times, when
doing work in another techs shop that didn't have a winch, etc. Worked just
fine. They can be rented and are not that difficult to use/set up.
