I like the single rudder and maybe single board idea, It may not be the right solution but it is something I would like to try.
It is much simpler, is familiar to a mono sailor and is cheaper.

Simple to use yes as there is only 1
Cheaper from a foil aspect also because there is only 1 of each as well.
Cheaper as a whole -No - as you have to create mounting and deployment fixtures on the cross bars which before were simply a plain round tube. This complicates the platform considerably both for use and the build.
