I apologize, I'm not familiar with technical details, may be stupid,
only general thoughts:
-overlapped block sizes - two blockchains, uncertainty, unpredictable
results, trust gets down
-non-overlapped - single blockchain, determined growing, everybody
knows the schedule what and when will happen
A minimum block size does nothing to prevent the problems that come
from schism hardforks.
But also a minimum block size can be trivially cheated as recently
explained on this list:

Hi,
As I understand the main problem of the fork Core<->XT is possibility
of double spending:
-I run XT and spend my coins
-it is written in 8mb block
-Core does not accept this block
-I run Core and spend my coins again
-it is written in 1mb block
-but XT accepts this block too
so
-in the XT block
