I like your list, but I see 2 likely problems with what you have:
1. There are 8 relatively easy kill points between the Speeders and the Crusader squads sitting without transports. I personally have 21
kp in my 2000 pt
BT list, but other than Speeders which are relatively easy to kill, all my units are meched up.
2. If you have an objective mission, slogging 5 Initiates across a table without transports to grab an objective is not gonna get the job done. In addition, everytime you move that unit it will not get to fire its
ML.
Take a look at my list here:

It is also a missile-heavy list, but where yours is a primarily foot-based list, mine is speeders and mech, which can withstand horde assaults and dish out some punishment.
