Phil, I had also considered restuffing the cans on my set. Things got real crowded under the chassis where I mounted the replacements. If you ended up with the same 160uf caps as I did, I think they were physically too large to fit in the original cans. A good solution may be to restuff the original cans with the smaller values and then mount the 160's underneath? By the way, I didn't experience any interference as a result of moving the electrolytics underneath...
I hope you will do one of your famous write-ups on the CTC11 set and post to your site. Always enjoy reading your restoration articles.
