I gues you are having a very bad day at heavy weights and at a hot/high airfield to loose 2 on one side ...
The only likely scenario is a multiple bird strike, or a uncontained blade that took out another eng.
Accelerating to clean up is logical ... I've been on type for 1.5yrs and their is no published procedure for this scenario, to the point of 'it wont happen' - never practiced it in the sim. (If if it can - it will is my theroy).
I've been faced with gear stuck down and an engine out (dispatch with 1 or 4 demand pump u/s and loose 1 or 4 eng respectively), the gear overide switch locks the gear lever ...
Heard it said gear stuck down is as good as loosing another eng. in terms of climb performance without the directional issues.
