You could, however, use 3 henchmen squads, a cheap
HQ, nd 3 ravens, and then ally in blood angels, with a cheap librarian, 2 5 man assault marine squads, with a dedicated Raven each.
You could probably squeeze that into 1750, but while the gunships have a lot of killing power, you are basically only running 5 vehicles and minimum troops vs a whole 1750 point army.
Edit - Turns out, blood angels don't get it as a dedicated transport either. So....Nope xD
Max you can have in a 1750 army, is 4, 3 basic, one allied.
Could ally with space marines though, get 4 ravens and one talon
