I like where you're heading with this, but I don't think it will happen, for a few reasons.
1. As you said, importing the game will be a big challenge, but I don't think you said it correctly. I think what you meant was that it would be a big challenge that just wouldn't work out. Remember back when Blockland last got an update? It might have been a bit recent, but mind you, during that gap of time, it took a long time for Blockland to actually get updated. Now compare that to the time it take's to transfer the game onto console, and you have something that may never get finished.
2. Blockland was a game developed for the PC and most likely just for PC. Sure Minecraft got onto the big systems (PS4, Xbox, Wii U), but that's really only because it was released as a new game in 2011 on PC, just a year before it got a release on Console. Now say for other games, like Blockland, which was released in 2007, and the even older Roblox, being just a year older than blockland. These games were just meant for the PC, specifically because of the large amount of commands the game would need that even a popular fighting game with alot of command inputs just wouldn't fit. Minecraft probably got onto systems because of a few command inputs required to actually enjoy the game. That kind of stuff just won't work for Blockland.
3. Blockland is different from Minecraft and Roblox for two reasons. One, Blockland has a different approach of audience compared to Minecraft and Roblox. While those two games are mainly aimed at kids, Blockland takes a goal at around the teens, which may be the reason this game plays differently compared to the other two. Two, Blockland just isn't as popular as Minecraft and Roblox. Minecraft's popularity pretty much earned it's release on consoles, while Roblox, while only being on Xbox one in terms of consoles, have lots of kids playing on the usual RP servers, or obby servers, or whatever they think of doing. Blockland however, has barely anybody online anymore, and in cases like these, good steam reviews just don't matter, simply because Blockland, and I really hate to admit this, may start losing interest, which is what makes it different from Minecraft and Roblox. Of course I'm not saying either or is better, but if a game isn't popular, it most likely won't be ported anywhere else except it's home.
TL;DR: Blockland would be close to impossible to recreate, the game doesn't seem popular enough for a port, and there would be too many inputs to try and configure.
I'm sorry if it seems like I'm ranting, but I just wanted to give out my two cents on this.
