It's not the only solution but surely the easiest.
The semaphores that would be required are already
in place (they are used for checking readyness now).
The complicated part could be switching between the
two regimes. I suspect this can't be done 'instantly',
it could require a multi-step process spread over a
series of periods.
Maybe I'm overestimating the complexity, but I try
to step gently as organising the cooperation of these
threads was not a simple task. The code looks simple,
but that's the result of my usual irresistable urge
to simplify every algorithm down to its essentials.
I've not really tried to solve this ATM, but will do
if some free time drops from the (currently) blue
Italian sky.

non-RT, while these extra threads remain at RT.
So
they will pre-empts Jack's thread and will appear to
be always ready on time. Except when you have 2 CPUs:
then Jack's thread will be allowed to continue even
if some of the others have not yet completed their
work.
Wouldn't the easiest solution be to wait for the worker-threads when in
freewheeling mode?
