Nah, not totally bonkers, but it work, if by light tourer you mean a very small pair of pannier or bikepacking, then that ratio work well for the majority of ride, you got a decent range from 109GI to 33GI.
Haven't decided on the route yet, but will stay clear of insane steep hills.
When is the Shimano cassette coming out?

33GI is a little on a high side (28GI is usually idea), but as long you don't have any alpine climb to deal with, If you don't mind not being able to descent fast (panniers won't let you go more than 70km/h I notice), a 40t chainring would be apt.
FWIW, my fixed tour is 65GI with bikepacking, was a little spinny on a long flat route with tailwind but acceptable for everything else.
