Absolutely, pretty much one of my most wanted. SSC said at a SDCC panel two years ago they would definitely be finishing them but a lot has happened between then and now. I see Zuckuss from Mediacom come up every now and then but holding out for SSC to do it.
Bossk with exclusive snarling face is still one of my favorite SW figures I have. I like IG too but his arms are a bit floppy and he doesn't hold his weapons very convincingly. He is standing more to the rear of the shelf looking over everyone.
I almost got the Medi 4-LOM droid hunter but then I saw a few pics that showed just how undersized it really is compared to SSC figs and decided against it. The Hasbro one - with a little work - can look pretty decent and is correct scale. Hasbro Zuckuss is so good you almost wouldn't need a SSC one, maybe for a more accurate gun. Only issue is the pleather is going on all those (can be fixed with paint though.)
And yeah - I've found SSC IG to be a bit of a "set and forget" fig. SSC went all-out on the articulation (probably too much) but the joints don't seem to endure much reposing before starting to feel a touch loose. Also, don't extend/unextend the legs too much as it scratches the weathering paint, and be very careful of the tiny pegs that hold the weapons in place in the hand grippers - they aren't quite properly positioned so they are too tight and can break.
