That's the plan!
And I tried to attach my test drive videos but the files are too big, it looks like we're limited to 64MB and the smallest of the videos is 66 MB, and they go up from there. So here are a few final pics instead. The first two are shortening the trumpets, I took off 5/8". The consensus seems to be to remove between 1/2" to 3/4" so I went with 5/8" Actually it was a hair more after finish trimming to get them all of equal length.
