Oh, and as for those pages you linked: They look pretty complex, with nested templates again, so it's probably not easy to recreate that perfectly - in case that is desired. But one can do so in Cargo as well, by using essentially the same technique of having a template deal with the output of data, instead of one of the automatic processes.
However, if we are to try to get more unified templates here anyway, and maybe deal with the overly complex (and slow!) Define etc template chains, it could make sense to do these things simultaneously.
Sort of independent of all this, do you know if the current templates are using the structure from the game's XML files, and if the data is mostly updated?
If we are to do this, we could make sure the templates (and pages) use the same structure to make them easier to maintain -- within reason. Perhaps the XML files have way more data than we need.
In any case, there is some background info here: Gamepedia policy thingy. I was active over there at the time, and it was quite amazing the amount of issues SMW caused for them. The entire network, meaning every single wiki, could go down for hours on end because one of the larger wikis carried out maintenance on the SMW database. Which eventually led them to effectively banning SMW.
And here is a brief migration guide that is useful to refer to: SMW migration guide.
Since I've done this once before, I can do a lot, but it would of course be excellent with some help as well, as it's not a small task. And I hope to be able to use much of the code I wrote for Pillars. Templates and infoboxes can probably largely be re-used.
