I think there is likely to be some resistance from monarchist Tories whose loyalty to the Queen is even greater than their loyalty to themselves and power. I don’t think they are great enough in number to do very much considering how completely selfish the Tory party has become- but anyone who might wish to oust Johnson in a few years time may use this sort of behavior to hurt Johnson and to make claims of how they will be a change from what had gone before. According to Wikipedia the work of the committee can be transferred to another, rendering the original committee redundant.
UK Supreme Court could likely intervene, presumably applying exactly the same irrationality test and invoke precedent set by  UKSC 41, quashing the prorogation on the basis that it is clearly intended to frustrate Parliament, especially considering “external” events like a member of the Conservative party being expelled. And in case of a recess, as far as I know, ISC can still sit during the period, despite not being a select committee, and considering the report has been cleared for release, it can be released as soon as possible. At the least. They have zero qualms about bending the rules til they snap like palm fronds.
