Advice needed, please!

I'd like to understand if there is a better way to approach this. My questions are here, followed by some background. Is there a better way to approach this with regard to mapping out alternative solutions to management? Are there any tips for having that conversation? Is it worth it to mention interpersonal issues, or should that be something I keep in my back pocket as a secondary reason later, if needed? How can I fight my brain with regard to the trust issues and really settle back in if I do stay? Note here that I hope to only get super creative answers on this one - I tend to ruminate and get very anxious over these things. Fellow ruminators and anxious folks - thoughts? I work in consulting and I have a hybrid role as a consultant and a subject matter expert representing my department on all calls with prospective clients (or current clients with prospective projects). This role was a pivot from my years of clinical operations experience in that I got to develop a new skillset with contracts and business while still keeping my clinical skillset sharp as a consultant. I started at the company about a year and a half ago with a few promises: they would never make me be a part of sales. They know I'm not a salesperson and that is not where I want to be. they would allow me to build out the role they would make me a leader on their clinical team and eventually move into people management on that team as well. Since I started the company has been in a state of constant change, culminating in layoffs recently. Layoffs were followed by 3 sr. leaders resigning in the last month. The company is in panic mode and just announced that they will be moving me into...you guessed it...sales! I am a biologist with over 15 years of experience in clinical research and zero years of experience as a salesperson. My last role was Director level and I am an AD here. I've never had any performance issues, received the most acknowledgments from peers in my department, and have been called a "star performer." That is bad enough, but they want me to report to an old-school sales guy who has been very condescending to me and another woman in the same situation. He is a micromanager, has been caught in many lies, and has nothing to teach me (about my personal career trajectory). I have not yet brought this up as an issue and am focusing on the issue of not wanting to be in sales because it is more compelling, is 100% true, and is in line with what I told them when I was interviewed and subsequently hired. After telling me about the restructuring, I found out they don't know if my title will change if my compensation will change, what my possibility for development and future growth would be, or even what would be expected of me. I requested more info but told them if they forced this, they can expect my resignation. I don't want to be difficult and want to offer other solutions. I'm working on a powerpoint to present creative options to them to try to help solve the issue. I'm feeling really stressed over all of this. On one hand, I don't want to leave. I don't want to look for another job and was previously happy enough at this company to stay long term. However, with the recent trust issues I have with them and the clear lack of respect for me and my autonomy, I worry that any solution aside from actually resigning may not work. Thank you so much, in advance! :)
