Inversion/without inversion - correlative conjunction ( just as ...... so )

[Barman]

Please consider my sentence below.

1) Just as I love birds, so does my brother love aquatic animals.

In the sentence above, inversion in the second clause has occured after so.

Is it grammatically correct to write the sentence without inversion? For example:

1) Just as I love birds, so my brother loves aquatic animals.

It's a very old style; so old that it's hard to judge whether it's correct or not. No modern writer would use it. I'd write I love birds. So does my brother.

 

[probus]

But the brother doesn't love birds. How about:

I love birds. My brother loves acquatic animals just as much.

The sentence without the inversion is the correct one.
