@Microfinne, there is a chance. Each chassis is going to handle things differently as it sends its signal down to the yoke. Who knows, might just not sync and you'll be unscathed. Might just blow up. If it blows up think about the cost to repair your chassis. Even if you have the skills to do it yourself, you are probably going to look at $35-$50 in caps and parts. All of this to find out if it will work or not. Here is a better +EV proposition for you:
The BSide Pro is $25 bucks. If you after you measure your donor and come to find that it is not within 10% of your monitor specs, then you can just conclude you have to do a yoke swap. If you decide not to do the yoke swap, you are looking at re-terminating yoke connectors. Doing that properly is going to cost your $4 in connectors. Not doing it with connects requires you to splice, solder, and insulate. After doing that, it might still not work. Now you have to resplice, resolder, reinsulate the original connector to the monitor yoke.
Net/Net: BSide Pro is $25 and a worthwhile investment if you are going to do tube swaps. Will save you time and money.
