would their weight be any different?

Wow, you do produce big bubs!!! IMO they would have got a little bigger but not too much, maybe a few more ounces. Your body won't grow a baby it can't birth, the wonder of mother nature.

I had DS at 37wks 3 days and he weighed 8lb 3oz, the MW said he prob would have gone to close to 10lb if he had gone to term!!! Both DDs were born on their due date and weighed 8lb 7oz so I do have big babies. I am 5"4 too and weighed 63kg at 9 months pg with both the girls. (I wish I still weighed that LOL)

They definitely would have been bigger, but probably not much. My second DS arrived 3 1/2 weeks earlier and was exactly one pound lighter than DS1. I dread to think how big he'd have been if he'd gone another 4 weeks!
