Very reasonable list.
I really dislike Lysander but whatever floats your boat.
I think you would be better off with razorbacks than rhinos. You have an
ADL to die the combat squads behind. Then they work well with the pred and gunline approach.
I would usually suggest taking 10 sternguard so you can combat squad, but I guess with Lysander there, that is not your plan.
Lysander
TLs their bolters, meaning you get a third more hits.
A cheaper way to get more than a third more hits would be to take 3 more sternguard.
Very reasonable
