This is what I've been doing only I shifted my ride to be earlier. I have two options for going over I-94 that don't add a lot of miles to my commute. I work at 7:30am so I'm leaving my house at 6am, crossing the freeway at around 6:15am. There's very few people on the road that time and so far I've yet to have a problem staying in the right lane. I'm sure I'll get my fair share of honks and yelling in time, but I'm also lucky to live in a relatively bike-friendly town and most people (not everyone) respect that around here. Glad to hear you've figured out a good method for timing the lights, good luck and stay visible=safe!
