Our Parents- is there a need for them to meet?

Hi Guys, This isn't an issue that is life-threatening or relationship testing but am looking to get opinions all the same. My boyfriend (who I'll refer to as B) is 28 and I am 25. We do not live together, but I would consider us reasonably serious. We are both committed and want the same things in life, both have similar values in regards to family, etc. B has just purchased his first home, which I will not be living in. This home is to renovate and sell as an investment property to enable him to afford a better home in the future. I'm very proud of his drive and focus, and am happy for him that it is finally happening. B suggested casually this morning that "We should really get my parents and your parents around so they can meet. Maybe we should host a dinner party or something." My first thought was "Holy crap neither of us can cook." But my second feeling was dread in the pit of my stomach. As mentioned earlier my family are very important to me, and I love my parents dearly. I also really respect and admire his family, his Mum and Dad are lovely. Do you think they need to meet? I am of the opinion that if there was to be an engagement, or pregnancy if that happened first, or joint home ownership, then that would be reason for them to meet. Or what would be even better is for both sets of parents to be at an event (B's birthday or at Christmas etc) where they would all be there and could mingle without the pressure of forced conversation etc. TIA.
