A more practical DD wheel/tire pkg for 335i?

I've put some thought into this after mounting my winter set... looking at my fronts (Blizzak) it looks like if I really need to drive in snow I probably need to change fronts, after only one season of driving (they were on the rears last year.) I do have access to a better pair of used tires so I can get through this year, but I'm thinking about this... everyone who's tried them has been very complimentary of the Continental DWS. They are available in a 245/40ZR17 size; rim width is specified as 8" to 9.5"; max load is spec'd at 1356 lbs. whereas the rear GAWR of an E92 is 2348 lbs (so the tire max weight rating is more than half the rear GAWR which is greater than the front.) Rolling diameter is listed as 24.7" whereas a 225/45 is 25" (recommended winter size) and stock Bridgestone 225/35ZR19 front is 25.1". Stock RFT load rating is 1235 lbs. front and 1356 lbs. rear.

My winter wheels are Style 157s which are 17x8" ET34. So theoretically I could but a set of 245/40 square DWSs on there and stop messing about with changing wheels/tires twice a year, and I'm hoping that they would be adequate in the light snow that we tend to get here in DC-land and if I wanted to drive up to PA and heavy snow was forecast I'd just drive my Jeep Cherokee instead. I also assume that I wouldn't have such a crashing ride over less than optimal road surfaces that I currently get with my 19" staggered 230s and stock Bridgestone RFTs, nor would I worry so much about curbage.

So... does this seem like a viable plan? Would 245/40s fit OK in the front with an ET34 wheel? Am I thinking all crazy? In an ideal world I'd be running PSS in the summer and Blizzak in the winter and I'd have a servant to swap them whenever conditions called for it, but I'm thinking that implementing my idea above whenever I need new tires and just storing the 230s for if/when I go to sell the car might be a better idea.
