Maybe, but I think we're going to hear specific noises and American interference first.
Plus, both PLAN and PLAAF requirements are in fact rather urgent, China needs LO strikers(and any naval LO) ASAP.
China literally lacks 1st day aircraft as of now - jamming, drones and J-20s as sensor nodes are good, but you also need just a survivable bomber.
J-16 isn't exactly one.
Apart from being a cheaper plane (and perhaps slightly stealthier?), what would make the J-35/A a better striker than J-20? Is it purely opportunity cost, that being that J-20 is too few and thus precious to spare for the strike role?
For LO striking, we roughly know the depth of J-20's IWB but we've never seen J-35/A IWB, and its length and width look similar from compared photos. Are we expecting J-35/A IWB to be deeper? Have there been any credible rumours on this? J-20 IWB seems too shallow to carry anything other than thin A2A missiles.
F-35 is a better striker than F-22 because it has deeper IWBs, better sensors and integration, and has EOTS (while F-22 does not). None of these differences may be present for J-35/A vs J-20.
Even for non-LO striking, we've seen photos of J-20 with external carry of munitions and as a larger plane it should be able to carry more externally, so the J-20 can do better in that role too (but moot anyway as J-16 exists).
(Obviously for PLANAF the J-35 being the only LO option altogether makes it an important new addition. But I still fail to see why PLAAF would need J-35A purely for strike, except on cost grounds).
