I definitely would if the river level was lower as I suspect many others here would. I have long thought that the use of stepping stones is a 'lost art' in the development and design of our Access Network. Probably a victim of the too safe interpretation of safety ideals, so that little scope is allowed for the user to exercise personal responsibility.
There some huge stepping stones that cross the River Vyrnwy at Dolanog, which walkers of the Glyndwr's Way may have spotted, though rather hidden and a rather long jump apart. Probably extremely ancient as they are so smooth (water-worn) that even dry they are risky. But the nearby old and near bridge have rendered them obsolete many years ago. It was these that first started me thinking how stepping stones could transform summer walking, making many fords that have lost their right of way status into valuable strategic crossings.
It would be possible to design a hand rope with a collapsible post, using a shear bolt at mean water level, with manufactured stones such as these. Clearly, the coarse aggregate near the surface has been quite skilfully tamped in at the finish so the stepping surface has grip. The other advantage would be that they could all be cast on-site from a well-designed mould.
There would be a wonderful opportunity to avoid a nasty road crossing of the A458 near Llanfair Caereinionion and bring the beautiful Maesmawr Estate into the cross Britain walks, but the potential of this route is too hidden by lostways and other lost opportunities through the lack of creative thinking.
I thank the OP for a picture of an excellent example of a valuable walking asset. Were more of these assets bought to the attention of those who administer our access network and their value studied and evaluated, then some progress might be possible in understanding how access can benefit both user and occupier.
