If you give her a shorter morning nap (shorter than 1hr, more like 45mins), the afternoon nap will be earlier and bedtime shouldn't be as late as 7.30pm.. if you prefer to give her a longer morning nap, you could look at something like this:
6am - wake
10-11.30 - morning nap (I would probably wake at 1.5hrs)
3-3.30 - afternoon nap
6.30 - bed
Or something like that? Because the pm nap is only short, she should hopefully be ready for bed sooner.
I prefer the shorter am/longer pm nap but that's only because it suits us better.
Generally though they do tend to have a longer day when they are in the transition period
