you can do the unfilled R4's solo. i did, and i weigh about 150lbs. i just kept them upright, not sure how heavy they are to lift if they fall over (probably not too bad). when i got both off, moved it around to the other side, leaned against hub and adjusted the jack until i could slide them on w/o lifting.
hardest part for me was finding a good spot for the jack stands. everything is so tight, there weren't alot of options for both the stands and the jack at the same time.
