I would it assume it would be ok to use my current sub along with an upgrade.

Not recommended. The problem is, over the limited range of the inferior sub you get twice the output, because the better sub covers that range as well. But at the lowest frequencies you only have the single, superior sub operating all by itself. Thus what you typically find is that overall performance is compromised. Or, like our Moderator brucek is fond of saying, when you use two mis-matched subs, response is “dumbed down” to the lesser sub.
