Weddingbee boards

I'm not a fan of cake, so we're thinking about doing a wedding pie buffet instead. We're thinking of having 2 choices, strawberry-rhubarb and apple crisp (not the weird, glue-y rolled oats kind--the awesome crumble crust kind like my mom makes). I checked and the cake-cutting fee (it's like $50 total which is awesome) can be applied to the cutting and serving of pie, no problem, and all the waitstaff is included in the site rental/catering fees. So that's not an issue.

Now. Logistics questions: We are looking at a reception for about 200 guests. I know. Ugh.
I like the idea of having the buffet table loaded with pies with a little sign noting the flavors. Like these: http://100layercake.com/blog/archives/1101

However, your typical round pie serves about 8-10, necessitating 25-30 pies (20-25 with no overage). Is this totally insane? Would the wait staff totally hate my guts for asking them to coordinate something like this? I know it's silly, but I don't really like the idea of having the pie pre-plated. It reminds me too much of being at a cafeteria. Would doing half cake/half pie be a better idea anyways, so I can have a cake and eat my pie, too?

Anyone ever been to an alterna-dessert wedding? Input and thoughts greatly appreciated!!
