I do not see problem. However, an opener is created for opening discussion, you must not eternize this phase. The point is to getting a hook, allowing the creation of a real dialogue. I have seem people approaching with too long openers, consequently they went nowhere... Take in consideration if you are in night game that noises might be certainly an obstacle, and if you game in day, that busy life rhythm can force you reducing opener.
So, if your combined opener allow you reaching the hook point, go for it because it's the essence of a good opener
Btw, your combined opener sounds good to me in point of "fluidity"!
