It is possible to very crudely simulate the architecture of these with plugins like that, yes. But you won't come anywhere near the sound of a broadcast processor. The reason is that they are studio type effects, and are not made to be program independent. That is, they don't adept very well at all to the material at hand which is what broadcast audio processors do very well.
For the most part, compression for studio use is still back in 1939 with the invention of the Pro Gar. Sure some advances have been made that removes some of the problems, and the control signals have been improved, but same basic idea in the grand scheme of things.
One compressor that was created for radio, that ended up now getting studio time, is the Gates STA-Level. It was the first compressor that gated itself (stopped the release) from increasing the gain if the input levels fell below a certain point. Thus allowing the compressor to be driven harder and faster without having the typical "gain rush" during silence. I think that was 1955 when that came out?
By 1956 there was the Gates Level Devil which is superior in noise and also adds a "return to level" function which will slowly increase the gain after a hold time has passed so that the gain can return upwards even if all of the input audio is under the threshold. As a safety measure mainly.
And as you can imagine the innovations kept coming and coming and coming. In fact there are analog boxes that still have more features than the latest digital boxes (yet sound inferior to). Aphex 2020 MkIII is a great example of a great sounding analog box.
For instance just between MkII and MkIII there was more than 40 improvements made, and the box still uses more patents than any other broadcast audio processor out there.
