The only way a SUBCON.FDS sequel happening will become even a possibility is if at least the following takes place.

• Someone makes a stable, well designed Super Mario Bros. 2 engine...FOR Gamemaker Studio 2. I'm never going to touch clickteam for any long term projects ever again, so if this were to happen, someone would have to make a stable Mario 2 engine, with at minimum, all the features of the original mario 2 on it (e.g playable Mario, Luigi, Peach, and Toad, Subspace potions, buried vegetables, buried items in general, pausing, doors, locked doors, etc.). But since no completely engine currently exists...no Super Mario Bros 2. Engine made specifically for Mario 2 style gameplay and it not being for Gamemaker Studio 2, no sequel.

• There also would have to be some kind of other strong incentive other than just a few people asking for me to do it too. Given how, at the end of the day, these are fangames. Fangames don't pay the bills. And along with this, I'm really busy as is, and don't see a foreseeable time in the future that I won't be unfortunately, and so, unless there's a way I can do this where I'm gaining some kind of transferable skill from this (Since I'm currently eyeing Gamemaker Studio 2 as an option to make a lot of my future games on.). It becomes less likely. Another possibility too is that Luigikid hosts another Exechallenge and I submit a sequel to SUBCON.FDS for it. It certainly isn't going to be this challenge, seeing as I already have a game planned for it (to be announced at a future date.).

• Basically in summary, SUBCON.FDS is VERY unlikely to get a sequel, and it's something of which I will only consider if there's a really big demand for it, someone does something to optimize the process that would be involved in making it, and if that method of doing so was on Gamemaker Studio 2.
