Wouldn't it work by just parallel wiring a new thermostat assuming the OP
has TRVs on all the radiators?

No, because the 2 stats will not do the job they are intended, in
fact, I'm not really clear on exactly what you're suggesting but it
won't won't work anyway.

If you have TRVs on all the radiators then all you need to know is if the
conservatory needs heat.
If it does you fire the boiler.
You do this by putting a second stat in parallel with the room stat.
In fact you could have several stats if the layout needs it.

I think its a bodge but TRVs are a bodge anyway.
