OpenSM gen1 has a nice TCL API (named osmsh) that lets you do all that and much more.
Setting ALL options is supported.
It also provides a Tcl access to the SM Database so you can write your own reports on FDB/MC-FDB etc.
Interactive control on the discovery and fabric settings sequence allows "single stepping" too.

The OpenSM user manual provides extensive description of it, including some programming examples.

Porting of osmsh to gen2 should be very simple.
I do not see why we need to invent yet another way to do these things.
Instead I would recommend including osm Tcl extension in the gen2 trunk and put it to work.
