A few points here -

The Timmins station is indeed silent, but that's irrelevant; as long as 
it remains internationally notified, it still has to be protected.

That's not what would keep WJIB off 750, though. The existence of WVNE 
on 760 makes 750 unusable anywhere in eastern Massachusetts.

Here's the relevant FCC link, to part 73.37 of the rules -

http://www.hallikainen.com/FccRules/2007/73/37/

For first-adjacent daytime operation, WJIB's 0.5 mV/m contour couldn't 
overlap the 0.25 mV/m contour of WVNE, and vice versa. WVNE's 0.5 mV/m 
contour encompasses pretty much all of Greater Boston.

720 would have worked, once upon a time, and in fact there was a 720 CP 
in Billerica that was never built (and which, when it disappeared, made 
the 720 in NH possible.)

The winning situation, once upon a time, might have been for WVNE to 
have gone on 720 (if suitable protection to WOR could have been 
arranged, which I'm not sure about) and for WJIB to have gone to 750, 
where it could likely have had at least some night power with 
appropriate nulls to Atlanta and Newfoundland. New Hampshire might then 
have ended up on 740 (though the international protection to the 
Canadian Class A would have ruled out night operation, so it couldn't be 
licensed as a new station under today's rules.)

That ship has long since sailed, though.
