Here's what we know:
1.) You broke from your own plan and elimnated any way for us to confirm that you are not a godfather. Your reasoning is that it would be too risky for a godfather to do this because there is another family, but I disagree. One family learns everyone's roles and has control over any inconsistencies to root out the other mafia all for the cheap, cheap price of a single mafia member. Additionaly, it almost takes the town completely out of the game as they will sit back and wait for you to make all their decisions with all of your information.
2.) You have no way of confirming that you are not a CK without sacrificing our probably last DT, if we even have another. Without role counts, we can only guess.
If we take you at your word and hope we have a DT to sacrifice to "confirm" you, we still have 2 big problems.
1.) The timeline is off. If our DT used his rolecheck as early as possible, he won't have a RC available until night 4. This means that in order to confirm you both you and the DT have to survive until then...
2.) Night 4, the DT rolechecks you and you come back as Vigi. Does he announce that in the thread? How do the rest of us know that he is actually a DT and not a mafia member? We can kill him to confirm but that will take either another vigi hit or we will have to wait until the lynch on Day 5.
3.) Those of us still alive then send our roles to you on Night 5 and you look for inconsistencies. Who do you trust to pass this information off to in case you die?
It would require medics to stack on you for 2 straight nights, while the mafia is free to slaughter the rest of us. It requires the last DT to survive, if there is another one. If there isn't, then the medic stack will be so very bad for us.
Can you propose a faster timeline than night 5?
