Sliding Harmony

I’m composing a harmonic progression. I think it sounds pretty good. But there’s a problem. When it loops around, it would sound better if the last chord was a semitone higher. So I want to transpose this last chord. But at the same time, I want to maintain the original relationships between this and all of the other chords. How would that be possible?
