Personally, I can't see anything that would prevent the government from proroguing Parliament for a shorter period, declaring its intention to prorogue or allowing committees to continue their work until prorogation. Once prorogation is over, there is nothing stopping members who support the government from working together to follow through with investigations that were under way before prorogation. To my mind, all of those things are possible.
