Integrating st60+ wind to a STng environment

Hello,
I'm updating the electronics on a sailboat from ST60+, it has installed three displays with its transducers, wind, speed and depth.
I will install an EV1 wheel autopilot kit with the p70, an I70s and a MDF a65. Also I have an ITC-5 and a St to STng converter.
I would like to keep the analog wind display, I need to know the best way to integrate it, to use the wind information on the STng and also to be able to have the VMG displayed on it.
May be it is not a good idea.

Thanks
