I would have to think that your ground psi would be more on the wheels of the triplex than on the head of your rollers. Although you have 80#+ in your design per head, you equal nowhere near the weight or psi of a typical sidewinder roller. But, if this is your only option, than I say it's better than nothing! I rolled with a set of triplex mounted rollers for years just because it was my only option. Just don't expect the same results compared to a sidewinder roller.
And to answer your question, we used to fill the buckets of the triplex reels with sand and go "roll" the greens. So, I would figure those things weighed probably close to 80# with just the sand in them and an additional 70# or so for the weight of the reel itself. We never had any issues.
