Old Faithful for Open War?

I think I want to stick with Blood Angels for the forseeable future, but the awesome power of the Thunderfire cannon keeps pulling me back to Codex Space Marines. Seeing as how none of you were particularly inspired by my last Blood Angels lists let's see if this grinds your gears:

1750pts of Codex Space Marines

HQ
Librarian
TDA, Storm Shield w. Gate of Infinity & Null ZOne

ELITE

HEAVY SUPPORT
Land Raider
2x TL Lascannon, TL Heavy Bolter, Multi Melta, Extra Armour
Thunderfire Cannon

THe basic plan is gunline it and use the Terminators to counter assault or gate about with the Libby to cause trouble. Basic Scout Squad go in the Land Raider, now I have an AV14 scoring unit with good ranged fire-power, the lascannon combat squad supports the TFC in the backfield, hopefully in reinforced cover. Camo Cloak Missile Launcher Scouts are a relatively hard to kill distraction and the melta combat squad are inthe las-plas razorback ready the go wherever they are needed to threaten heavy armour or elite infantry. The two Riflemen are self explanitory, the sit at the back with the typhoons and dish out dakka, and the melta speeders suicide towards heavy armour or are used for blocking.

Any thoughts from the cloud?
