IMHO yes, it is. Remember that some units don't require Spores, such as Genestealers, so you can shave off some points that way. I'd probably add in a mix of Trygons and Mawlocs, as they pack a real punch as DSers. Trygon Primes double as Synapse, so three Trygon Primes and Three Mawlocs sound like a great way to start off such a list. Each trygon will set you back the cost of a Land Raider if you also give them Adrenal Glands, a ittle more if you give them Regenerate. The Mawlocs are cheaper.
To that, I'd probably add six Harpies with TL Heavy Venom Cannons, giving you nice Long range firepower. And since they are flying MCs, cheap for what they are, they can go in and kick some in melee.
That would fill your Heavy Support and Fast Attack slots, but you've still got around half the points you mentioned for elites, troops and headquarters. Just remember that you want those bonuses to your reserve rolls, and fill out the rest.
