Not my speciallist subject I must add, but I can't see it happening. Terrestrial based ICBMs are housed in concrete silos which can tolerate the high temperatures and pressures of an initial boost-phase motor, as well as accommodating ducting for the exhaust gasses. Can't see that on a surfaced sub where the weapons are packed in like sardines, and I don't know how else you are going to get the missile far enough from the host vessel to avoid damage.
