It's more appropriate to own a MacBook for every room in your house, including washrooms. I would suggest that instead OP.
My setup:
2019 MacBook Pro base model running
30 real time data intensive charts, around 50 live real time data feeds, as well as 7 live video feeds all at the same time 10-14 hours a day. I need this setup to be portable
AND
12” MacBook 2017 model when I have my MacBook Pro docked to the side. I use this for everything else such as replying to emails, etc
Is it appropriate to own both given my usage?
I heard the ideal portable solution is to carry as many machines as you can within a portable wheel driven suitcase.
The issue isn't how man machines you have but its actually the bag you have.
Let me explain, the bag you have dictates how many machines you can carry with you.
Therefore picking the ideal bag will dictate how many programs and machines you can run at any given time.
As @556fmjoe says, run one program per machine. So if you find the right bag / case to carry one machine per program you are set. No more slowdown or risk of your MacBook Pro running too hot.
I've taken the link to this thread and added it to the Wikipedia article for "humble brag".
If portability is a requirement, then there are some solid battery powered monitors that could be used as a 2nd display. Not only are they cheaper than a 2nd laptop, but will take up less space.

Can we see the "30 real time data intensive charts, around 50 live real time data feeds, as well as 7 live video feeds" you have? Facebook and twitter don't count.
