Not at all likely as [IIRC from discussions in uk.railway] current mainline

Really? I'd be surprised if you couldn't open both sides
separately[1]. Unless the "close" buttons close all doors regardless
of size, in which case you'd need more staff to watch the "wrong" side
when closing.

[1] You definitely can on 321s, as these can often be seen in
Bletchley CS with all doors open on both sides, presumably during
cleaning.
