[sblock=On Bards and Rogues]... or something like that.
Anyway, a couple clarifications, if I might.
Firstly, every leader's 2/encounter healing ability costs the target a surge. Bards are at no disadvantage there.
Secondly, the leader multiclass feats all give that class's main healing ability 1/day, not 1/encounter. If it were 1/encounter, then they'd be half as good as the real thing!
Thirdly, and this isn't a mechanical thing, the god of rogues and thieves and gamblers and ne'er-do-wells in general would be Merkari, our equivalent of Hermes/Mercury. No need to propose something new there

Of course, if you'd like to invent a new as-yet unknown demigod who is your cleric's patron, that's fine.
I think the idea with our pantheon is that the Twelve are the gods. (Period, pretty much.) However, since it's a copy of Greco-Roman mythology, there can be demigods out the wazoo. Pretty much anything you can dream of, there can be a demigod (or demigods) for. The demigods in Greek myth always had at least one divine parent, but we could probably waive that - divine ascention of mortals seems to be a sort of obsession in D&D circles
