Just need to upgrade the hardware to something more modern. Any mid-grade or better low-flow toilet made in the past 10 years or so can flush a lot of TP without any difficulty. Some of the early low-flow toilets weren't particularly good at it, and the high-flow toilets from the 70s were amusingly bad given the sheer quantity of water they use. Also, encourage people to use bidets. Those are the best.
