Yes, it is far fetched. If the Chicago Outfit has 30 Made guys with 120 full time associates, then Detroit has maybe 15 to 20 made guys and 60 to 80 full time associates.
They were always similar to Chicago except smaller. They have always been traditionally 1/3 to 50% smaller than Chicago.

Ivy's estimate backed by the Feds information of Detroit having 30 made guys in 1996 would correspond to the Outfit having about 50 active made men back at that time which is what Nick Calabrese stated in the Family secrets Trial. Again, this is 1/3 to 50% of the total.
In addition to all of this, there has been very little activity in Detroit as far as street rackets. It's been more legit and white collar like the Elmwood Park & Grand Ave crews in Chicago.
Some of the guys that The DETRIOT poster thinks are made are probably relatives of former made men running legit businesses just like in Chicago. Detroit partnership is not all of a sudden bigger than the Outfit. There is no evidence to support it. Yes, Detroit Partnership is one of the 10 Mafia Groups still active in America. No question.
