I knocked up an 8-line epg screen for Blue Two Wide for myself a while back, which can be found here:

and, on request, I also created a 6-line epg screen, which seems to be popular with Australians, which can be found by following the link from the first post of the above thread. From your screenshot I can't tell if you have a 16:9 or 4:3 setup, and I'm not sure how well they'd work in 4:3, but they're probably worth a try.
Don't forget to back up your original screen file first!
