The simplest and reversable fix is to lift the trigger past the first stage with a pad of devcon. I did this to try the idea in1978 or so with the intention of threading a screw in instead to make a neater job but this has worked well for thousands of rounds, first on the origonal 30-06, then a 7x61S&H and now for 800plus rounds on my own 404 jeffery plus countless dry fires. Certainly worth a try and you get a nice 3lb trigger. I liked it so much I had a nicer blade made but the basic trigger design is very good. Nice old Lewis by the way.
