The issue your going to have is that artillery will be a liability as your main army will get to grips with your opponent and then your basilisks will be sat twiddling their thumbs, or worse, missing and blowing the holy moley outta your points expensive bikes.....
Try command squad kitted out for short range in a chimera, two vet squads with demo charges in chimeras, then 2xbanehound1xdevildog as your fast attack slot, this will soften up them big meaty swarms and has a nice hidden MELTA in it, heavy support you could try the griffon, which a fast, mobile little artillery tank which can re roll scatter dice, or try 2xdemolisher1xpunisher leman russ tanks, which are tough, effective at mid/short range and can deal a LOT of hurt, if your hq is Usarker E Creed they can even outflank your opponent....
