Anything I can add to show building Inspector? (photo attached)

Im looking to open up the floor plan, and would like to remove the center load bearing wall. I have talked to a few contractors and this is what we've come up with, the rafters are 2x6 and the roof is a 5 pitch. There is support in the basement. Columns every 8':

I would like to avoid having an Engineer come in, I know the building inspector will know if it will work or not. Any suggestions would be greatly appreciated. Please keep in mind I am not a contractor or engineer, so please don't laugh at my drawings!

@Ben Sears has the basics down on an approach I’d also recommend however this forum is not the place for speculation. If you don’t know how to calculate the load on the LVL then you should get some help from an architect or engineer. 

I’ve done this process in several homes and it’s the AOR/EOR ‘s liability on the certainty that the load will be held by a certain size beam, post/support combination. 

By the way, I’ve not seen more than a 3-piece LVL utilized in this type scenario, therefore limiting to a 5.5 may not work.. but I ask you why you’re limiting yourself to this depth? The LVL doesn’t have to match the joist that are attaches to it. This is a pretty simple and straightforward thing for a pro to handle, however you being reluctant to hire an engineer (or architect) is making you spin your wheels with speculation and however much time you’ve been trying to figure this out. @Brian Ellis
