I don't know how far you are willing to go, but I have a feeling you will accept some crazy and silly stuff.
I like the twin gods idea, but I would do it as twin sisters who think and act as one. They combine their powers, making them very strong. They're not utterly identical, but they are close enough that you can't tell without being extremely observant. They're the goddesses of dance, fencing (all three kinds), and bait fish.
I went to Pompeii once, and saw that picture of the guy with an arm size **** on a scale. That would be a pretty good god, as a god of fatherhood, and gigolos. Lesser known as the god of paternalism.
Neutron, the neutral god, of neutrality, and disinterest (but not uninterest). "I have no strong feelings about this." There are no order and chaos gods, only the god of neutrality. He would be annoying, but he never feels strongly about anything, so he doesn't have a wacky crusade to keep an arbitrary balance of power in the unviverse. Prayer and sacrifice can bring his favor, allowing a person's perception of neutrality influence the world, or to bring neutrality to their own thoughts, or the thoughts of others. That also makes him a meditation, and relaxation god, to a certain degree, beacuse you can't actually enjoy yourself, or feel good, but you won't feel bad either. It also makes him extremely useful for certain medical proffessionals, those possesed by inquery, and judges.
No death god, take the suprisingly practical approuch, with people giving it no mind beyond it being a natural part of the world, not to be worried about. If it has to be mystical, it can still be a natural system in theology, not actually controlled by a particular god. Doing that also avoids Santa syndrome, where he as to be everywhere at once, or super fast.
Annually, on the most ironic day of the year, this god gives surprisingly perceptive gifts to those who don't deserve them, as well as extremely generous gifts, which he thinks are ironic, to the needy, but which everyone loves. He laughs because no one understands the joke, which isn't any good anyway, but he doesn't care. He is also the messenger god, and theif god. He's not fast, just everywhere before anyone else.
This god is one of a species of land based, photo synthesizing, meat eating, plant cephelod which died off millennia ago. Breeding occurs by a male injecting a subject, leading to mental and physical alterations, which in the mortal form, drives the subject to seak out a female of the extinct species. If successful, the female uses an ovipositor to implant an egg, without killing the host, which has been driven to produce the male's sperm, in a process similar to how virii convert host cells to produce more virii. Once combined, a second mental and physical change occurs, driving the subject to find a hiding place, where it will eventually be consumed by the maturation process, and any remains are eaten by the young. Additionally, pheremones are produced to drive off predators. As the last remaining god of the species, breeding cannot occur, but the drive to breed cannot be contained... it will strike out at any creature within range, and because of its godly nature, the control and changes which occur are completely, and continuously, controllable by the forgotton god. It is possible to comunicate with the being, but extreme caution must be taken.
