I'm sure there is, but I'd be looking at pressure to then dictate tire width, rather than the other way around. For me, running 30mm tires at 65f/70r offers a great balance of comfort and performance; I'm sure that you could get away with lower pressures on 28s.
Then again, this is coming from a 190lb guy that was used to ~100psi on 25s, so while 70psi may feel like riding on a cloud to me, a lighter person that regularly runs 85psi might be less impressed and want to go lower. IOW, personal experience will shape preferences and it's hard for others to guess your sweet spot might be - I would think that the pressures afforded by 28s would do it, but until you try it, who knows?
