You haven't said why you want to change from those zooms. If its image quality, I note you have a 7D. If I were you I'd get a 5DmkIII - you'll notice a dramatic difference over the 7D. The IQ of my 7D was less than the 5D classic (which I subsequently upgraded to a 5dMkII and which is worlds superior to the 7D).
Primes are nice, I love them and use them parallel to my zooms.
But as someone suggested before: if IQ is that counts, take a FF first.
My 2 cents.
5D3 with zooms would be better than 7D with all the primes.
FF + 16-35/2.8L'II ~ APS-C + 10-22/1.8
FF + 24-70/2.8L'II ~ APS-C + 15-44/1.8
FF + 70-200/2.8L'II ~ APS-C + 44-125/1.8
APS-C + 14/2.8L'II ~ FF + 22/4.5
APS-C + 24/1.4L'II ~ FF + 38/2.2
APS-C + 35/1.4L ~ FF + 56/2.2
APS-C + 50/1.2L ~ FF + 80/2
APS-C + 85/1.2L'II ~ FF + 136/2
APS-C + 100/2.8L ~ FF + 160/4.5
APS-C + 135/2L ~ FF + 216/3.5
TS-E 17L or TS-E 24L instead of 14L'II (for landscapes and architecture)
24L'II is fine
Sigma 35/1.4 instead of Canon
40/2.8 STM - a must-have
Sigma 50/1.4 instead of Canon
85L'II is great, but 85/1.8USM is fine (while smaller and faster AF)
135L is nice (better than 85L on APS-C)
Sigma 150/2.8 or 180/2.8 OS Macro instead of 100L, 180L and 200/2.8L'II
