By changing from 11T or 12T to a 14T in the rear, you may be saying that you don't need the highest gears.
And changing from 28T to 34T on the rear means you want lower gears.
You can achieve some of the same by going with even a smaller crankset. 48T/30T? Smaller?
Ultimately you could probably keep the current 12/28 cassette, or even go to 11/28.
