Dude. I don't think you're the only "oddball". The previous responses in this thread prove that there are others that feel the same.
I think it comes down to how "ok" you are with being unique.
For my own costuming and props, I always try and do someting a little different. I enjoy that uniqueness.
My most recent (and best) prop/costume endeavor was for something which, as far as I can tell, I am the
only person doing.

I mean ... I enjoy the Iron Man movies, but I have no desire to cosplay it. Sometimes it feels like it can be a bit of a treasure-hunt on The RPF to find cool threads about work that
isn't Iron Man!
I love Star Wars. I made a jedi costume several years ago, but I have no desire to be just another stormtrooper.
I once showed up at a Halloween party, and there were TWO of us dressed as The Dread Pirate Roberts. How frustrating!!
One of the most unique costume threads I've seen on here was a guy who built a costume for Ted from "Bill and Ted's Excellent Adventure". How cool is that?!?!?
Have you ever seen that ComicCon photo of 30 gold-bikini-Leias standing around the Jabba the Hutt model? Each one of those girls was gorgeous, but none of them stood out individually, because there were 30 of them dressed exactly alike.
If you make the costume that a LOT of other people are making, then you'll have a ton of support from other costumers doing parallel research .. but in the end, you'll be one of many many guys in Iron Man armor.
If you do your own thing, you're going to have to figure it out all on your own ... but you get major cool points for being the only one doing it.
Now ... that said ... there's such a thing as going too obscure. I'd LOVE to do a Middleman costume, but I don't know how many people outside my immediate circle of friends would 'get it'. So long as at least a few people at the even you're attending will know what you're dressed as (ie. know your audience) then I say go for it. Be unique and have fun with it.
When I wore my WH12 costume, I had to explain what Warehouse 13 was to probably about half of the people who commented on my costume, but I had super cool positive responses from fellow WH13 fans when they saw my Tesla and my purple gloves and put it all together.
