You'll be more than fine if you use winter tires. Don't worry about it.
My accord is much lower, doesn't have AWD or even an LSD, and has zero problems in deep snow with winter tires (General Altimax Arctics) fitted. I regularly would push it through headlight-level snowdrifts. I used to have a front lip on it too. After a foot of snowfall, I more or less plowed the SUNY IT campus down to a depth of 3 inches wherever I went.
After a ~10 inch storm:

Last winter we didn't really get any snow in the Albany, NY area, so I didn't really get to play with the legacy much (although it was glorious when I did).
