With a compact, the trick is to shift the front and back together. E.g. when I shift from the little ring to the big ring, I also shift the cassette down 2 gears. It quickly becomes a habit.

With a triple, the gaps aren't as wide but are still there. I don't think you'll get any real advantage, unless you want to get much lower gears.

And yes, you'll have to swap out lots of parts -- bottom bracket spindle, crankset, possibly the front derailleur.

I say the best thing is to adjust your technique. It won't take long to get used to it.
