of course it'll work fine, i'm not 100 percent familiar with super t but in other forks they pretty much remove a couple spacers and add a longer spring no? your fork will be the same height as if it where in the 7 inch space *i think so anyways ;p* you might even decide you like the way it rides with the 6 inch fork on it only one way to find out
it takes like 20 min to install a fork throw it on there and see how it feels.
