Limiting morning nap to get a long afternoon nap

[*Natasha*]

So my DD2 7months all of a sudden over the last few days has started taking 45min naps (haven't had a problem with these since 2months old). So i know this means that it is time to extend her awake time. She was doing:

7.15am - Wake (i often have to wake her)
9.30am - Nap 1.5hrs
1.15pm - Nap 2hrs
6.30/45pm - Sleep for the night

I don't want to move the afternoon nap any later than 1.30pm as her sister goes down at around 1ish and i am selfish and want some me time  I follow her cues so if she is looking for a nap earlier than the above times i put her down. She dropped her catnap at 5.5months and is happy now with 3hrs awake time before bed.
So has anyone been in this similar situation where they allow the morning nap to be 45mins so they have a nice 2-2.5hr in the afternoon when older sibling is napping?

Well Natasha people do that sometimes to gear up for the 2-1 transition but I don't know how well it would work with a LO as young as Mirelle. But your girls are so darn easygoing that I bet you'd be just fine.
