There is no difference in the wing, so at the same weight there really shouldn't be any difference? Just my assumption. And if I'm not mistaken the braking system, I.e. tire and brakes, are the same so stopping distance shouldn't really matter either.
The 319 has slightly less powerful engines (unless your Bhutan airways) so you might see a lower flex temp, but the thrust would end up being the same.
319 has a slightly larger rudder But slightly higher Vmca speeds at certain alts and Configs (one or two knots difference) but they shouldn't really make a difference at those weights, they star to get limiting at very low V1s (111 knots and below).
Interesting question though, unfortunately I don't have access to an LPC anytime soon in order to get an answer.
