chainline <> front derailleur.
different cranks are designed differently so that they required different BB spindle lengths to achieve the same chainline.
I think these would work well for you; providing an additional set of choices.

I would consider changing to a closer ratio cassette, if you are not using the whole gear range.

Both my red and blue commuters are 7 speed; my green GT is 8 speed. Most of my projects this year have been 7 speed. 7 speed derailleur equipped bikes are still sold in more volume than all the others choices of speeds combined.
