I was addressing my comments to OP; sorry for the confusion.
But, to your point, I personally believe in the axiom "Mo' speakers, mo' better." I never have less than 12 speakers engaged (including SW) in any listening mode and enjoy the "bubble" of envelopment from this setup. I watch movies in Dolby Atmos/DSU 7.1.4 and listen to music in DTS Neo:X 11.1. Your preferences may lie elsewhere.

Where there's a will, there's a way. I'm not saying that you should have SB's, just that it is probably doable.
Without having seen your room layout, I'd wager that you have room if you're willing to move some furniture and/or speakers around. For one thing, the surrounds are going to be further to your side than the SB's, which should be directly behind the MLP. Also, if you needed additional separation in relation to the SB's you could move your surrounds slightly forward of the MLP; or, assuming your surrounds are at ear level, you could position your SB's slightly above ear level (up to 1.25 times the height).
At any rate, if you were to replace the A1's with A3's up front, I would experiment with reutilizing the spare A1's as SB before parting with them.
