That made a lot more sense with regards to that which you are trying to achieve, however.
This may not be the best of methods, but I personally, from that description you gave, would go for something akin to the following setup.
Rather than having a second large VO tank, (as mentioned by someone else above), fit a small ancillary tank in the boot/underneath for the diesel supply, and use the main tank for VO. Enclosing the fuel lines in an outer coolant jacket line(s) from the tank as far upto the I.P/engine as feasibly possible. The in tank heater you've already mentioned. Possibly a heat exchanger in the engine bay that can use both electric/coolant methods of heating the VO. Once the coolant system is upto temp, the VO is around the optimal temp, (although some do suggest it needs to be quite higher in temp to truly become akin to diesel), so around then the switchover to VO should cause no problem whatsoever, whatever the external temps.
The main factor you personally need to cover is the complete heating of the fuel lines/system.
There are most likely better or other methods, but something along the lines of the above would be a system that I'd personally be content with.
