Hi, Bill (and hi to Jack)!

My short answer is yes - grin - I use the same leader for 3 to 5 wt lines. I'm using polyester (Unithread) in a 10-8-6 thread taper, the leader butt around 5 1/3 feet long and then about 4 feet of 5x tippet, mostly for trout and blue gills, smaller bass and landlocked salmon.
