If my math is right you should be able to drop one of the Volkite russes and both of the sentinels to make the changes to the list I recommended, though you won't be able to get hunter killers.
Also just realised you dont have a command vox on your veletaris squad. Without that your vox interlocks do literally nothing so don't forget that in the future.
One final thing, if you don't mind fliers you might want to take an Arvus for your Command section. That way you can start with your command squad off the board so they don't get vapourised by a single Scorpius.
