I am a notorious string-mixer.
My opinion/advise/position on this is that you should pick a set that you think will work for you and put it on or better yet, if you've been away for a while, have a luthier put it on and adjust the soundpost and bridge to get it dialed in. Break them in, live with them for a while before thinking about making a change. If it doesn't work for you consider a different set. When you get to know your bass well enough with a few different sets, you could decide that there is some unique gremlin that could be chased out by mixing and matching from different sets.
Having done that and reached my conclusions about my own bass, if I got a different bass, I would put all of those conclusions aside and start over with a complete set. It can be an expensive distraction and isn't always necessary or advantageous.
