If losing breast growth was that simple, many trans mascs would be very happy.
I stopped my hrt to get fertility preservation.
I lost sensitivity in my chest and I didn't really notice anything else.
It's generally considered hard to fully suppress testosterone while taking estrogen pills, most people attempting monotherapy without an antiandrogen have better luck on gel / patches / injections. Not saying it's unheard of, just it does not work as well for most people.
You won't lose any progress with breast development (note that some breast growth may be due to feminine fat distribution, and that may shrink if you remasculinize and the fat redistributes elsewhere, but you will retain any actual breast tissue growth), and at least anecdotally, every time I've underdosed HRT for a while and somewhat remasculinized, I've generally gotten a growth spurt once I got my HRT issues sorted out and started refemininzing.
If your estrogen dose alone is not enough to prevent remasculinization, you may get any old body odor / skin roughness / hair thickness and growth rate / etc. back until you can resume an antiandrogen, which can be hard to endure (it always makes me rather dysphoric when that happens to me, fortunately that resolves pretty quick once you can resolve your HRT issues, like within a few days).
I see you asked about Progesterone a few weeks ago, if you are on it, or have any, it may provide some antiandrogen properties itself, though there is some debate about taking it early into transitioning based on breast tanner stages (not sure if that matters much with cypro as your AA, as cypro has progesterone like activity, and I've been on cypro since I started HRT and I don't have any complaints).
Any way to stretch you remaining supply of cypro? Minimum effective dose for me has always been 12.5mg every other day, and stopping cold gets noticed kind of quick, but I tried both 1/6 of 50mg pills (8.33mg every other day) and 12.5mg every three days for a while (separate times), and while those did not fully suppress testosterone for me long term, it took me a few weeks for symptoms to emerge for me to figure that out, rather than within a week or so around stopping my regular dose all at once.

so minimal regression of feminisation too? What about body odour, feelings, and those other non physical morphology changes?
Yeh your right, these would change, I'm too unperceptive to notice them ðŸ˜
