Sure, though I didn't mention that the J-35/31 could enter serial production next year, whether that be naval-based or land-based variant. I just mention "quickly".
However, speaking of land-based variant of the J-35/31 - The fighter jet has been undergoing numerous flight tests since 2014 (in various iterations and improvements over the previous ones, of course). Besides, there has been zero instances of any J-35/31 being tested in naval environments, which means all flight tests conducted so far are land-based.
Therefore, if anything, I think it is fair to say that a land-based variant J-35/31 is much, much more ready for introduction into PLAAF service than a carrier-based J-35/31 for PLANAF service ever would, even if Shenyang has no initial plans for the J-35/31 to have a land-based variant. Hence, as previously mentioned - If the PLA CMC demands the land-based variant of the J-35/31 to be delivered to the PLAAF ASAP, Shenyang has little reason to say no.
Heck, if the Chinese leadership views that war will break out in the WestPac within the next 1-2 years, who else in the PLA CMC and PLAAF cares whether the land-based variant of the J-35/31 is actually fully ready for service beforehand? As long as the land-based J-35/31s can function like any fighter would, they would be sent to the frontlines anyway - and Shenyang would be ordered by Beijing to hasten the remainder of the land-based J-35/31's development - Or even transform straight away to serial production ASAP.
Can you chill out with the "war is imminent within a few years" theme that you're making across so many different threads?
If you want to discuss hypothetically how XYZ project may or may not be able to be fielded within a given timespan, then that's fine, and if you want to relate it to a hypothetical conflict within a given timespan that is fine as well, but speaking about it with such a sense of panic and fear isn't really useful for anyone.
For us doing geopolitical observation and military watching, by nature it means that we are interested in a topic that if things were to come to a head, they would result in significant deaths, destruction, and upending of the world we live in and likely yield personal effects as well, and perhaps even result in our own deaths or deaths of our loved ones.
Please make peace with that knowledge so that we can talk about other things in a more calm and less panicked manner -- that applies to everyone by the way.
In the case of J-XY/35 or a land based variant, if the goal is to get a land based variant in service within two years -- if SAC dropped everything else to redirect resources to it, then sure it may be slightly possible, in the sense that at the end of the two years they might be able to get a small handful technically "in service". Half a dozen or perhaps even a dozen airframes, that are relatively immature, and lack the tactics/training/procedures and lack the logistics/support network to make use of such a small token force.
If this question is meant to be "how can the PLA maximize their 5th generation fighter numbers within two years" then the best way to pursue it would be continuing to ramp up J-20s given it is in production and s much more mature product.
Back in the real world, as it stands, we are not even fully sure if the PLA will still pursue a land based J-XY/35 variant for itself as a land based 5th gen complement to J-20 given how many J-20s we expect them to build.
And even if they do pursue a land based J-XY/35, and it makes a maiden flight tomorrow, it will likely still take 3 years of flight testing (or more depending on how many modifications it has from the standard carrier based J-XY/35), and true mass production will only occur by 2027 or 2028.
