susy GSW model?

Can anybody hint to some review of supersymmetry including the GSW
model, ie no quarks, only leptons under SU(2)xU(1). Or is there some
fundamental obstruction (besides anomalies, in any case) to build it?

A SU(2) model could be enough.

What I am intrigued about is that in such models, the sfermions could
be arranged to form a octet, and then I wonder if susy-SU(2) implies a
SU(3) "flavour" in the sfermions.

Such model could "scale up" to three generations, and then 24
sfermions to be arranged into a SU(5) "flavour".
