On the contrary, I think you should just focus on one type of sheet. Making a sheet that contains a sweeping generalisation of every information field ever just doesn't work, especially on a forum with roleplays so varied. Fandom roleplays have their fandom-specific information, squishy slice of life roleplays focus more on the sexuality and angst points of a character, etc. There will always be different sheets for different roleplays - it's not one size fits all.
