Alan,
My Ulster rep currently has 4.9 axle ratio and for a long time ran with 4-syn. I can't disagree with you but for me hill (mountain) climbing is important and I didn't want 3rd any higher. I have in fact just fitted a 4 speed crash box which is the opposite of the way you want to go, but it now has a splendid 'supercharger' shriek in second!
Your thinking is good, in my humble opinion. Drop to 5.25 to lower top and go CR to bring the other gears up. Or do as Steve suggests. It's very much a question of how you want to use the car though.
I'm not quite convinced about 17" wheels, theoretically yes but you might well find the rolling radius of a 17" tyre is as big as a 19", at least check before investing. I ran on 15's for a while but didn't care for them myself, too low (to the road) and very bouncy on the tyres they had.
