Well I can confirm it's do-able but I won't be doing it again in a hurry. Landed at A gates, bussed to half way down the B terminal to passport control, hasty trek back over to A gates for security to then be bussed half way to France and the remotest of remote stands with an entire bus to myself. Crew on inbound disinterested other than telling me which gate to go to, Crew on connection wouldn't even give a cup of water after my 1.6km trek (measured the wallk out of interest).
Slick operation in that my bag made it but not to be recommended unless you're in olympic training mode
