You can drop 1 raider in outrider detachment as all infantry hq and troops can already mount into 4 raiders.
I'd drop the five man reaver squad as this squad can not improve its toughness, i'd make a bigger 9 man reaver squad with 3 grav talons. You can then add another 5 five man haywire blaster squad for the outrider detachment with the points from the dropped raider and 2 reaver jetbikes. You still have 31 points in your pocket. Haywire blasters are effective against both vehicles and infantry squads. And can deepstrike later in the game to preserve points and increqase the pressure where you want.
With the 31 points you can upgrade two splinter cannons and 2 dark lances in raiders to four dark lances.
