I'd speculate not, at least not in the US. Here, more people have different types of computers (laptops, desktops, tablets, phones, set-top boxes) which are all united mainly by Web browsers / technologies. The Web is naturally - or at least, has been historically - more open and less conducive to walled gardens. Consequently, I think US consumers are used to the experience of getting news from (for example) the Washington Post, shopping on Amazon, and checking email on GMail, while navigating between these sites without too much hassle. This experience has largely been replicated on mobile devices, at least for me, despite the best efforts of Facebook and others to keep me locked in their app outside of mobile Chrome and Safari.
Since the Chinese government won't allow strong foreign competitors to penetrate their domestic market, I have to assume that Facebook, Google, and so forth are targeting other countries with these all-in-one messaging apps. Perhaps India would most resemble China's mobile-dominated market?
Tencent is what it is because competition is banned. China's "internet" is more like AOL from the early 90s, with network performance from the early 2000s at best. Nobody is going to be able to move in WeChat's direction because other governments aren't willing to erect massive censorship infrastructure to kill competition.
I was going to say I can imagine an app that combines FB Messenger, Yelp, Travelocity, OpenTable, GrubHub, and Uber. But WeChat already has all these things (either via companies they own or via partnerships).
Amazon also has Prime, so they can offer millions of subscribers incentives to prime the AnyTime pump.
