I think he is saying he needs 55 MORE sqr inches. ...... Run the numbers on your 2x6 frame and see what you'll gain. If enough, go for it. If not, it is not all that hard to tear out concrete or block. That is not necessarily a fun DIY job, but it can be done and you can likely hire a concrete cutter for a quick job like that (easy for ME to say "quick", as I've never done it! Sounds quick, though.) j
