At first, I thought maybe just switch out the small chainring. But I am thinking this crankset has a 110 bolt circle diameter, and from other discussions, the consensus is, you can't put anything smaller than a 34 tooth chainring on this crankset. So you could change out the cassette to an an 11 - 36 and that is pretty close. It gives you a low gear of 1.0, or just over 27 gear inches. Also switching out the chainring from 36 to 34 gives you a low gear of .94, or 25.8 gear inches. Leaving the Cross Check the same gives you a low gear ratio of 1.13, or 31 gear inches.
What to these numbers mean? Just switching from an 11 - 32 to 11 - 36 will get you most of what you are looking for.
