Wow! Glad my work was inspirational. For better or for worse the Tanith aspect of that army, for me, was aborted and the army has morphed a few times into what is now a Valkyrie-heavy Catachan vet army. Ennkay on the other hand, took what I started with and ran with it and completed a full army using the Wood Elf/Cadian conversions here:

If you want to do recon, there's a number of ways to do it - do you want to go the modern route and make it a force that uses the best tech it can? Or do you want to make it a low-tech, hiding amongst the leaves and trees recon force?
And, yes, at least for a recon force, 12 basilisks is too many. Now, if you want to make an artillery company, that's another matter entirely.
