Re-Framing a wrap around porch on Victorian home

Hi,
The decking and framing of our covered wrap around front porch is in desperate need of replacement (roof structure is fine). I am capable enough to install the decking (most likely Tigerwood T&G), but have been getting estimates on the framing, which have been outrageous, so I have been thinking about doing it on my own. The porch is an L-shaped wrap around, with the outer dimensions being 24 ft and 16 ft. It is about 8 feet deep on both sides, so I'll be using 8 ft T&G boards, and I want to install them perpendicular to the house on both sides, with a 45 degree seam at the corner.
My question is this: Could I run a doubled 2x12 beam parallel to the house and joists perpendicular to the house from ledger to beam, then install 2x10 blocking 16"OC between all joists so I can run the T&G perpendicular to the house?
It seems less work to do this then it would to run multiple beams perpendicular to the house, as I'd need almost double the amount of footings to do it this way.
Any advice would be appreciated, and if there's any additional info you'd need from me to be able to offer any advice, please let me know.
Thanks!

| Outrageous is an intersting term. Less work is also intersting. J. |

| Blocking is great for keeping joists in line and needed on large spans, but relying on them as "nailers" for the decking is asking for trouble unless you are willing to use hangers on every block in order to keep them from moving with use of the deck. If you simply nail the blocking, eventually they will settle and the decking will follow the blocks leaving a roller coaster deck surface. I think you would be better to run girders every 4',the girders attached to the planned 2x12's and ledger, and joist opposite/inbetween using hangers attached to the "girts". The girders can be doubled up joist material same size or larger,(2x12's same as your header/ledger). |

| Laying the decking with butt joints (parallel to the house) isn't all that bad. You're gonna have waste with or without butt joints. A clever trick on this MB with butt joints is to match the roundover on the planks to the end grain (probably 1/8" radius but could be more). Doing that makes all the butts blend right in. That's what I would do. |

| Why don't you just make the decking come of at 45 degrees instead of 90, then you won't have to worry about all the blocking and it makes for a stronger deck |
