no way or you getting 15's ported in there. Maybe 12's ported or 15's sealed.

Why not do one 18" Bl fully loaded?
2 12's - 226.08 sqin of surface area
2 15's - 353.25 sqin
1 18 - 254.34 sqin
Not quite as much cone area as 2 15's, but def more then 2 12's. If you are going SPL, the 18 should serve you better then two twelves, and it will be much easier to build a ported box for it then two 15's. Fi reccommends a minimum of 3 cuft for each 15. they also recommend a minimum of 5 cuft for each 18. But, I would Think you could get by with around 4.25-4.5 cuft with the 18. Thats 1.5-2 cuft smaller then the port box for the 15's. The 2 12's would need a box around 4 cuft anyways so its really not that much larger. Have you given any thought to getting a single 18" BTL? just my 2 cents.
