Default Question about time stretching/pitch shifting to key. Technique? VST?

OK, I'm relatively new to this, and sort of threw myself into the deep end since I figured that since I had written music before, this should be straightfoward. (I was wrong.)

OK, I'm looking to time-stretch/pitch shift a song or parts of a song. I've been researching VST's and techniques for it, but everything seems to be set to the idea of measuring it in bars/loops etc.

What I'm looking to: I have a song that for various reasons I am composing in REAPER that moves between Bm and the relative E Dorian. (specifically the other way around, but anyway).

The thing is, I want to, then time stretch/pitch shift it so that it goes to Am and D Dor.

Everything I see that does not go to bars/loops is for time stretching without altering the pitch, but I want the opposite.

So is there a VST or a technique where I can set something to time stretch by key? In other words, I want to be able to take a piece of music or a track in and tell the REAPER/a VST to "slow this down until it is in the key of Am" or "slow this down until it is one full step lower"*

*This may not be most music-theory correct way of saying it, but my background is in metal, so I'm thinking of this is as the equivalent of tuning down a a guitar or bass a full step so that playing in Bm/E Dor becomes playing in Am/D Dor.

Sorry if this is confusing. I literally took a week to figure out how to ask this question, because just thinking about it has confused me way more than it should.

The genre is a mix of witch house and gothic industrial, if that matters.

If I understand you correctly could you simply use Reapitch to change the pitch 2 semitones? Perhaps on an item by item basis?

Playrate = 2^(semitone difference/12)
Turn off “preserve pitch…”

Of course ascat is correct if you really do want the music's tempo to slow. I assumed that you did not want this as I misread (?) your comment ""slow this down until it is in the key of Am" or "slow this down until it is one full step lower".

Thank you both, I think I posted this in the wrong forum and wanted to move it, so sorry for the incorrect place.

But yeah, that is exactly what I was trying to figure out. I do want to both slow the tempo and pitch it down, so that should work.
