There is always a 10k at BUSA's for men and there have been some good runners who have competed in it over the last couple of years- AC Muir, Andy Norman, Mark Miles, Olly Laws, DJ Ricketts, Bobby Gould.
It is normally held on the saturday...so might not be as good for those of you down south. however, BUSA is held on bank holiday Monday weekend...perhaps you could persuade them to alter it to the Sunday.
Why not speak to UKA or try George Gandy (lufbra coach) and Bud Buldaro (Birmingham Coach) and whoever is control at St Mary's. With the distance universities supporting you I'd see no reason why it won't be staged.
