Mantis warriors all infiltrators 1500 points

40K Army: Space Marines

Okay so I am thinking about the following because infiltrators are cool and the FW mantis librarian guy is even cooler!
This list should really work tactically as I can setup my entire army after my opponent thanks to infiltrate, get re-rolls to failed seize the initiative tests, and I have a very good psychic power in mirage!


HQ
1 Mantis Warriors librarian special character, mirage (he and his unit get shrouded and any unit charging them counts as disordered) and nullzone. His stats are similar to a standard librarian but he has a 5+inv and can reroll 1 failed psychic test each turn. He has a force weapon, bolt pistol, hood, and is mastery level 2. Plus he gives your army infiltrate if they are infantry and don't have a transport!

Elites
5 Tac termies, assault cannon, Chain Fist.

Troops
10 Tacs, lascannon, plasmagun, combi plasma.

5 Scout snipers, camo cloaks.

Fast Attack
6 Scout bikes, combi melta, melta bombs, 2 grenade launchers.

Heavy Support
10 Devs, 3 missiles, 1 multi melta, power axe.

Total = 1500 points.


My army theme is that they are fast moving skirmishers and a successor chapter of White Scars descent. They prefer to surround their enemies and pick off the weaker elements before sending in the Terminators to finish off.

Do you think this might work?
