Virgin Mobile to o2 migrations

I understand Virgin Mobile cusomters are being moved to o2 - billing, branding, etc. - throughout this year.

Does anyone know of a way I can ask/force them to do that sooner for me?

If I can get it on sooner, then it will mean I get the benefits sooner: double mobile data and double VM broadband speed, all for same current cost.
