Does this 17"/18"setup seem like it will work?

I've read 17"/18" wheel and tire threads on here until I went crosseyed. I have a 72 duster, it has all stock suspension, KH front disc, 8.75 A body rear. I'm in the process of switching it over to BBP, and I want to go with a 17" wheel. For the front end, I'll be picking up a set of 74 duster spindles, and brakes. I'm also adding QA1 UCA's and a sway bar.

From my research this is what I'm thinking and tell me if you think I'm in the ballpark with fitment.

Front:
17x8
25mm offset
I thought about a 225/45 but I'm thinking a little taller and a little wider like a 245/45.

Rear:
18x9
0 offset
275/40

If I went with a 245/45 front and a 275/40 in the rear, that should give me the same size sidewall front and back. I feel like the 225, is just too thin. I would do 17's in the rear, but they don't have the correct offset to make it look staggered.
