You aint kidden-cowabunga-Hed be good for a second calf Im sure there are some stout ones in Canada too 
I used him on heifers and didn't have any issues./// What about the roan I posted here-Shes an Exile-but generations of Low BW prior-she weighed 75 pounds-but shes pretty stout-not good pics and in with some BIG and one really good simm Angus-shes as wide as they are 
Biggest calf we have had was 84 pounds out of a cow the throws big calves, and 84 was maybe the smallest calf she has ever had. I do think you would like that mating with your heifer, she looks pretty soggy.
