looks odd, but pack a good punch. putting those srm 2 on chain fire can give you a constant barrage and its like and ac 5 shoot to the enemy, due to the tiny spread.
I've just been looking at a very similar build, but from a different perspective: I was basically drawing inspiration from this thread, which was suggesting using 3 x SRM2s as "fast-firing SRM6". The 2D2 is an even better option because you can get a "fast-firing SRM8". The tonnage that this frees up over SSRMs or larger SRMs lets you mount a good sized AC with adequate ammo. Pairing the AC10 and SRM2s gives you two-weapons on shared cooldown, which is nice. Two medium lasers gives you a decent backup with some redundancy if you lose an arm. Cooling efficiency is a little on the low side, but if you forget about the lasers inside SRM range, it should be easily manageable. The shake idea mentioned in the OP is interesting and could provide an alternate tactical option, but I'm not sure how easy it would be to keep a stream of SRMs on target with their low projectile speed and limited range.
