If you are starting her day an hour and a half earlier, then she would likely be ready for bed earlier. Until she can adjust to the transition, and since you probably don't want a 5:00 bedtime, then you might have to give her an extra early evening catnap.
So, her day might look like this (I'm also writing it out for my benefit to try to help you, not that this is the right way):
6:30 up and bottle (although if you have to leave at 6:45, will you need to get her up sooner?)
7:30/8 solids
nap 8:30/9 - 10:30/11 (she is currently used to 2 hrs of A time from morning wake up, any more might be too much for her in the beginning)
10:30/11 bottle
12 solids
12:30/1 - 2:30/3 (this would be great as a 2 hr nap if she can do it)
3:00 bottle
5:00 dinner solids eventually?
(she actually could probably make it until bedtime b/c there's really no room for a nap, but if she's exhausted and conks out, you might just let her sleep for 30 mins)
6:30 bottle and bed
Since she will be loosing a bit of the nighttime sleep she's used to, she might just make it up in naps and be able to keep her same bedtime of 6:30. It's going to be trial and error for awhile until everyone can adjust. But, like I mentioned, if she really needs to snooze late in the evening, I don't think that would be a bad thing. Just not for too long. Sometimes, though, having that dinner can perk them back up to make it through the evening. Of course, dinner solids is usually the last to be added. Remember, you'll want to start slow with the solids. Some babies just are ready for them, so you'll want to watch for signs of upset tummy and of course allergies.
