Eh, why would it be cheesy? What, spamming Guard options with GKs support? Is that really neccessary or more cheesy than Guard itself? I mean, GKs are quite overcosted.. To be honest, the only thing worth taking from DH dex are Inquisitor Lord with Mystics and the Calidus Assassin. Sure that can prove quite nasty, but still, cheesy? I'm glad people 'round here never use that word and just attempt to take on anything you throw at them with a smile.
And the other way around? Well, DH codex does have quite a hard time doing stuff itself.
