Let's avoid any snark, please :). I'm not one to hold back either.
"Snark" is more likely in the postscript.
Now, about the main topic – your reasoning is logical, but it is focused on the wrong situation. You are reasoning like a developer of a new game, not like a modder.
Do a thought experiment. Suppose you wrote that version that you are planning. What will happen next?
Will all the Heroes community happily rush to play it? Not really... here, people are pushing TE-Lite with a lot of hassle for the SOD community, and your version will be even more different. Just one point – moving the word to the 2nd floor – caused so many complaints, although, in general, it's a minor thing.
- the target audience is not only SOD and TE players, but primarily newcomers.
- TE-Lite has problems – for example, a complex installation. I am going to solve this problem.
- a very significant advantage of the version will be simultaneous turn-based gameplay.
I think all these factors will encourage people to try the new version.
Next, predict the reaction of the TE players. I've talked to many, and there is no enthusiasm for reverting to SOD. As a result, people will discuss it, express their dissatisfaction, and me, Sagu, and Horn will have to create a normal TE gameplay on your engine.
That's basically the perspective... do you really need it? You'll just end up with problems; a smart person learns from the mistakes of others, and there have already been many such mistakes.
In my opinion, most TE players will switch without any problems. In fact, I want to abandon two things in TE – classes and experience. And even then, in a later version, compensate for this by adjusting skills.
"Creating a normal TE gameplay" can be done in parallel.
