Is this a viable option or does anyone recommend another direction?
You could do that sure.
Your stock tires are 235/40R18 which have an outer diameter of 25.4"
You would want purchase 215/50R17 tires which have an outer diameter of 25.46"
The difference is .06" which would throw your speedometer off by 1/10th of a mile at 65 MPH
Personally I went with 15" Alloys and 195/65R15 Blizzaks which has the same approx outer diameter as my stock 17" Black & Machined rims 215/50R17 tires. My speedometer is off by 1-2 miles at 65 mph. I paid 50.00 for the used rims and 371.00 for the tires (out the door) at Costco.
The 15s are cheaper and work better in the snow since they are narrower. They also have as higher sidewall which is better for pot holes, etc.
