Dark souls the boardgame on Roll20!!

No jokes here. I'n really trying to bring this fantastic (for me) boardgame on Roll20 and, with all the cards, tiles, tokens and boards scanned... Welp, I'm making it on Roll20. The problems are little, but some fantasy me and my friends can afford these: the character sheet/board will be on the map backgrounds, with all the tiles to play; The tiles are not optimized to a square grid-system; the enemyes and players tokens are not compatible with roll20; we need always some1 that will master the game, to use all the decks of the games; the d6 dice system is very unusual and without numbers but simbols... So, I ask somethings... If (when I end to build all the decks) the game will result playable on roll20, there will be a way to build a custom dice? A custom and interactive sheet? A 3D mode? A way to integrate some pdf (rulebooks) on roll20? A way to unable the grid system (if there isn't yet, in this case sorry for my oversight) A way to enable in some games that every1 can insert tokens, cards, decks, etc... Without the gm power? Thanks for your time and... Sorry If there are some gramma error and similar, I' m only a poor Italian guy that will bring him fantasy everywhere xD

I don't know the system, but you could mimic a custom dice by using  rollable tables .  If objects in the game don't fit nicely on a grid, you can right click > advanced > is drawing. This will make the object no longer snap to grid. You can also edit the map to remove the grid (under  page settings ). With a pro level subscription, you can make custom character sheets.  Here is a thread where one can issue requests for members of the community to make custom character sheets. Also, if there is nothing special to keep hidden from the players in this game, you can set everyone as a GM. That way they can drag out any tokens they need. I would recommend making characters for each token to speed up the process. You can't upload PDFs to roll20, and I'm not sure of the legality on sharing them.
