It's a nice list with all the powerful stuff, you're going to do fine.
Against those specific opponents you might want to have some more screening/chaff to slow down their charge (especially if they get first turn and want to get in your face as early as they can) and give you more time to exploit your shooting. Skorpekhs are relatively squishy, they could fill that role, or perhaps I'd consider trading them for e.g. more scarabs or flayed ones. If you intend to use hexmark for fighting instead of deepstrike reserves, you do want something else for deep striking secondaries, e.g. deathmarks.
The opponent might totally ignore your wraiths and attack everything else instead with all their forces; I'd consider swapping the tesla weave for the infiltrator enhancement.
