The list is all over the place and you have some very strange options
Terminator armour models can not go in rhinos.
Fast rhinos are cool, but really you are looking for razorbacks with suitable turrets.
DC with jump packs are expensive.
Then you've made the stormraven a huge target.
Bikers do not need cover from the rhinos, the rhinos need cover from them.
Try a priest on a biker, also maybe get more bikers to get them to work. They may be a good walking shield for your new razorbacks.
I actually quite like the idea of a tactical squad in stormraven
Seriously combat squad down to 5, equip the serg. nicely then give them priest and a librarian/chaplain in terminator armour and you are charging out for some cheap destruction.
