you can always buy a few different, larger outer chainrings ,
with the 22 as your low, say a 46~8, 34~6

110 74 , 24t is as low as you can go. 34 for the larger set.

I put in years of touring on a 7 speed 14-34t freewheesl, and a 50/40/ 24 crankset.

with the 11 and 12 t top cogs you don't need big gears
44:11 and 48:12 are both 4:1 ratios.
