Could I use this design but with the subs and port pointing up?

I want to build a box for my 2 12" Alpine Type R's with alot of spl and good sq, I'm currently running 1000rms on them and I want them to be louder and get better spl scores. I have them in a 1997 ford f-150 extended cab. I've looked for builds on here and I like the design Steve made for the 15" Mtx subs, do yall think that design will work with my type r's and make good spl scores? or is there a better design out there that I can use?
