Has there been a homebrew that uses the 4-ports of a Sears VA II?

It can't be done. The SVAII/2800, just like the standard 2600, can only support 2 joystick or 4 paddle controllers. The additional ports are just to use the paddle incorporated in the combo controllers that came with the console, because they aren't wired in pair like standard ones.

Is there a way to use the extra ports for joysticks? Perhaps a programming trick?

Nope, there aren't additional input lines on the SVAII/2800, just the usual 10 digital inputs and 4 analogue ones with the only difference that, if you select paddle mode using the switch on the console, they are rearranged across the 4 ports to make use of the special controllers which have a different pinout (only one paddle line per controller and action button on a different pin)

 

The possibility to have more than two joystick on the 2600 was discussed in the forums and it's indeed possible but it requires external hardware.
