That'll work great. The way I think of it, the reason the better caps are better is they are exceptionally smooth and consistent in the way they charge and discharge. This allows them to pass a signal that is both detailed and extremely liquid smooth at the same time. Where lesser caps sort of spark in quantum steps instead of a smooth curve. Large caps of high quality that can do this are very expensive. But they can deliver this smooth fast response across all kinds of dynamic demands. The little filter or bypass cap like you are talking can't do much for the larger swings. But most of what we hear in fine detail is very micro-dynamic swings that the little cap can handle. So in effect the bypass cap gives you the detail you need to make the fine stuff sound a lot better and as long as the big cap "below" is pretty good quality you wind up with a lot of the Deulund big cap sound for a lot less money.
I used this in my crossovers using Deulund CuTn to bypass Jantzen Alumen Z, which are quite good caps but not Deulund level, but with the Deulund bypass they get darn close for a lot less money.
I don't have time or money to painstakingly burn in and compare all these different caps so I go by the info on sites like the home made hifi cap comparison. Worked great for me so that is what I recommend, unless you have someone better to go by.
