I can't tell you if your idea is over the top but you wouldn't have hardly any competition in the area. The best gun store for service and knowledge I've found is Hyatt's on Wilkerson in Charlotte but their prices are high. Gander has a pretty good selection but the staff are just box retailers (except for their gunsmith, I think he is knowledgable). The indoor range would be way cool. I'm a member at the Iredell FOP in Troutman and they have a pretty good facility but all outdoors. I think the hoops you'll have to jump through to build an indoor range are going to be huge with lead abatement and safety. Keep us posted if you decide to to do something. I would defintely like to see a good gun shop and indoor range in the area.
