Regen with reverse switch on but going forward

[Alpegu]

Hi everyone, I'm hoping you can help me with some questions regarding reverse and regen:

I have a GM BLDC 5kW motor and a VEC300 controller on my sailboat. Due to the way the motor sits, the boat goes forward when the motor turns anti-clockwise. Last year, I had a DIY potentiometer throttle that didn't last long, so I've bought a hall-type throttle from Miromax. It seems alright but it can only be installed in such a way that pushing the lever forward delivers a lower signal, ie it sends a reverse signal to the motor.

Now, since this direction of motor rotation is what makes my boat go forward, it seems perfect. But, I won't get any regen as the motor will always be "reversing". I know I can swap the blue and green cables, plus the hall cables, to reverse the default forward direction of the motor, but that would mean that pushing my throttle forward would make the boat go backwards.

My questions:

- How can I keep the throttle in its current position, while still being able to get regen?

- Does shorting the reverse button just swap the direction of movement? If I short the reverse switch, will it just swap which way my boat goes relative to the throttle signal?

- Does the reverse switch even work with a hyperbolic throttle type, where you already reverse by moving the throttle backwards from the midpoint?

- If this is the case, can I short both regen and reverse buttons to "swap" the direction that the controller considers to be forward, allowing regen to take place?

Update: so far, I've been able to confirm that the reverse button does indeed swap direction of motion even with a hyperbolic throttle, provided I go to neutral first (makes sense).

When I short the regen brake button, regardless of spin direction, the motor stops quickly and I get the 17 beep alarm that I'd expect when regen is on (as seen on other posts). Whether this actually recharges the batteries or not remains to be seen, as the motor isn't yet connected to the propeller, nor indeed is the boat in the water yet.
