Which heavyweights would've gone 49-0 if they fought the same opponents as Marciano?

I disagree that Marciano's era was the weakest ever. I would say this era tops it. Name me 1 atg or hof fighter that Wlad the current champ has faced? None. Marciano although faced them when they were past their prime, but at least they still had something left and were ATGs and HOF. Can you say that about Wlad?

I agree today's is weaker. So was the division during Dempsey's reign (of course part of that was because he killed a lot of guys before he beat Willard).

There has only been 2 great era's for heavies, 70's and 90's. Every other have been poor to weak.

That's simply not true. From about 1905-1919 you had Jeffries, Langford, Johnson, Wills, Dempsey, Jeanette, McVea and George Godfrey. In the 1940's you had Louis, Bivins, Ezzard, Elmer Ray, Tami Mauriello, and Walcott. In the late 1950's-early 1960's you had Sonny Liston, Eddie Machen, Zora Folley, Ingo, Valdes and Cooper. Each of those three eras were a whole lot better than weak, though of course not the equal of the 1965-1975 zenith.
