Stable channels aren't about downside protection, they're about convenience. If you want to save in fiat, there are far better ways of doing it than putting funds in lightning. Having fiat in lightning is so you can spend over lighting without (or, while minimising) a) having to think about exchange rates; b) having to calculate/pay capital gains tax as a result of making purchases. If you don't mind doing those things, stick with btc channels. If you do find those things a pita, having a modest fiat balance in lightning, at the cost of not getting the benefit of btc rising on that balance, and the risk of losing fiat value if btc falls too far is probably worthwhile.

If you hit the downside limit on a fiat channel, your customers don't leave broke, they leave with the btc balance of the channel, ie they "bought the dip". Even if they didn't end up buying the absolute bottom, that's historically still had a good outcome in the long term.
