2 Fi X 15' box help

[s5300]

If anybody happens to find some spare time in their day, could you please do a quick mock-up of a PORTED box design for 2 Fi X 15's in this trunk? http://imgur.com/a/ZXN6h

I'm fine with going further back into the trunk when the protrusions are, it would just have to be accounted for while building.

I'd seriously appreciate the help for anybody who is willing to give me their time. I'm thinking of changing an order of a 15' Fi BL to two 15' X's, but I'd like to see how it would fit in the trunk/how much room it will take up.

These dims will work:

Fb = 34 Hz
Vb = 7.6 ft^3

External Height = 17 in
External Width = 39 in
External Depth = 28.25 in

Port Width = 6 in

To try to avoid building inside, build a cardboard test box, keep changing dims until you have the largest possible that will fit from the outside and then post back those dims here, if not possible there are still other options like 3 12s for example.
