This all looks pretty good to me, very meta pick of units, will do quite well against just about anything SG are amazing now and 2W DC with a 5+++ (strat) will give your enemies a headache.
If it were me I would replace the sanguinor with a priest w/jump pack and give him master apothecary and the new WL trait for a free model rez a turn , though this is dependent if the codex will drop before your game. Another character to consider is a librarian in terminator armour to deepstrike and pop psychic fortress to give everyone that 5++, might be good, might be trash, but it's seems reasonable to me.
Astorath and Dante are good picks, as Dante can give full rr's to the DC (replacing lemartes who got nerfed too hard imo)and hit like a truck while doing it. Astorath is just a beastly master of sanctity- flat 3 D is huge.
Standard mope about erads being too good etc etc.
You can't fault intercessors, they are cheap (ish) and reliable enough across the board to get the job done.
Ngl it's looking very good.
