I don't know if you need Yriel. You could save some points by dropping him. I like Eldrad, but at 1500, he can be kinda iffy.
Your main problem is going to be a lack of firepower. I'm not familiar enough with Space Wolves in drop pods to know what he'll be taking, but you may need to upgrade those
DA squads to the 10DA+exarch+dual-cat+Bladestorm. Otherwise, you simply don't have much massed fire.
You could also switch those Scatter Lasers out for Star Cannons. Scatter Laser is typically better, but against
MeQ that aren't in transports, a Star Cannon actually works out to be better. This would be total list tailoring, though, so use it only if you're comfortable with that
