O2 : Extra sim

[kered10]

My wife and I are longstanding VM customers with BB, TV, landline. A few years ago I started using a V Mobile SIM, and the last time the deal was renegotiated I was changed successfully to an O2 SIM.
My wife uses a GiffGaff SIM.
I can't find anywhere on the website for VM or O2 whether there's any value in her switching to also have an O2 SIM within our overall package.
Any opinions?

She will just pay whatever the O2 price is, but will get double data as a benefit of being with Virgin.

Thanks, I think she's probably going to stay with GiffGaff.
