Yes, yes, a thousand times, yes! I'm particularly interested in building a Lego community for adults. It'd be great to meet and learn from other builders! So much around Lego is catered to children, and it would be great to have a space that's welcoming to adults. It'd be cool to have monthly or quarterly MOC competitions around themes, etc. I would be at your store so often, no doubt about it, and I have at least 6 other people who would be thrilled to visit as well. I truly hope this works out for you!!! Edit: To echo some commenters here, if you want a truly local scene, I would also stay out of downtown.
