Did you consider using STP? Are these switches RSTP capable?

You could create a low priority bridge acting as leaf node in the STP
domain. This will provide redundancy between different ethernet switches,
I just don't know if RSTP converges fast enough for your needs. Just be
a bit careful selecting the bridge's priority. A priority of 61440 will
be probably fine.

I am *almost* sure, that if_bridge works over if_laggs, perhaps you could
combine the two.
