Shoot it at ISO50-100. It looks a little greenish but nice :bsmilie: Ilford used to actually suggest this as an alternative to conventional B+W slides. Tmx100 slides looks much better, but more work than just simple x-process of XP2
Er, I haven't tried this but you might want to compare cross processing Tmax 400CN with XP2. The base of the Kodak film could be clearer. I'd expose it the same for a start.
