Doubling up on roles within the same job doesn't really work since it's still going to play in almost the exact same way: your GEO would still be using Cure for maintenance healing, Cure II for burst healing, Medica/Medica II/Cure III for the relevant AoE scenarios. About the only thing you're changing is getting rid of regen/benediction and replacing it with some ground effects, which isn't actually going to change much since you're still providing the GEO with a regen (except this time it's AoE). You're also beefing up their damage and healing/support capability (via the ground buffs) so that there would be next to no reason to actually bring a WHM since their healing is basically identical but the GEO brings more of everything else.

Jobs only allow for 5 new abilities to be added and minor changes to the existing abilities, which is why you're not going to see 2 jobs of the same role off of the same class or, as I'm pretty sure you've already discovered, new jobs off of GLA, WHM, or BRD. A job has to play in an noticeably different way for any others in that class, which won't happen without changing role, and it has to have enough abilities relevant to its role to make it interesting to play, which isn't going to happen with WHM because it's got too many healing abilities and too few of anything else.
