Alternatively, you could look into running a 205/50/17 tire instead to gain a little bit of sidewall. Better yet, switch to 16" rims and 205/55/16 tires.
As for freezing rain traction, I wouldn't expect any miracles there, unless you get studded tires.
QP - I don't think you really want to "gain sidewall" for the OP's 17" tires ... or you change the overall diameter of the tire...so, while a 205/50 is a little higher aspect ratio...the sidewall height isn't much different...and he doesn't want it to be, or you throw off the speedo, etc...
to the OP - 45 series tires don't ride well in general. The Continental DWS in 235/45R17 on my Volvo are a good compromise, great dry handling, good in rain, fair in snow (as good as you can get with AS)...and an acceptable ride...
