FCS Setup for quad/twin switchable

Sorry if this has been posted before, but since I saw Maz’s quad fish and a few of Pavel’s in SD I’ve been keen to make one, but I was thinking about trying to make it convertible between a twin keel/quad setup, more for the chance of seeing how the same hull reacts to two different fin setups than anything else, and also for an opportunity to compare the two in terms of performance and feel. Since the rear fins on a quad are usually less canted and toed than the fronts, I think that you could use the rear quad fins for the rear tab on the keels and then have side-by-side tabs up front, one on the outside for the front quad fin and one on the inside for the front keel tab. Anyone tried anything like this before, or have any ideas? Thanks!
