Hello! I loved reading this. It is such a nice thing to read in the morning.
First off, I would be in awe if you wanted to do a translation of some kind. I think translation is so cool, so by all means feel free to do whatever!! I'd even be happy with you sharing it if you wanted to. I'm also happy with you playing around with the rulebook however you'd like. You have the document, go wild.
As for the game itself, in my vision, I was thinking the expanded list would be you rolling 3 dice instead of 2, and it just giving you more options. So yeah, I thought of it as a something you could replace the original table with.
I think this was the first Expansion Pack I made for my games, so I think there are some things that are not as clear. I just recently did a sort of more fancy version of another game where I made it look nicer, so that might be something I do with this. I think having a sort of combined rules to make things like that more clear would be nice. So instead of base game plus EP, just having like a unified EXPANDED version that puts it all together.
