You will first have to figure out what you can actually add to that rack - Subaru went way proprietary with that rack system. Or are you going to go all the way and get the towers from Yakima that are adapted for it, and will take a variety of mounts for boats?
Yes, you will need to flip the boat on edge by climbing up on a ladder, but like the saddles you can slide the boat up pretty loosely rather than having to wrestle into position in Jbars. Honestly, every time we have considered the things I looked at the overhead of getting a boat positioned to slide up into them and decided it was going to be much harder than our stackers.
I am 5'3.5", 130 or less pounds and (nearly) 61 yrs old. I am fairly strong and healthy for that age, but I am still not going to hurt myself loading a boat if there is a better way to do it.
We did try saddles and rollers by the way. They went back into the basement within a year and we hauled out the old stackers, two reasons. One was that the saddles were a constant PITA in long trips - they just took a lot more frequent adjusment of the straps etc than the stackers had. The other was that we wanted to carry more than two boats.
