I didn’t check your math, but I suspect that you are correct when it comes to pixel dimensions. However, you’ll be using a much smaller are of the sensor for your actual image, which means (among other things) that is it equivalent to using a smaller-than-APS-C sensor camera with the downsides that come with smaller sensors.
Generally it is better to use lenses that project the image size you need onto the full sensor.
Basically, your approach could be OK for an occasional emergency situation where you don’t have a long enough lens and you have no other choice, but as a regular approach it isn’t a great idea. (OK, I’ll grant you that you could make very small images for things like social media use and probably no one will notice.)
Bottom line — you are getting the camera, right? Just try it and see what it looks like. If the results are good enough for you, so be it.
(From the sounds of your replies, which I have now read, it almost sounds like you aren’t here so much for feedback on your idea — which your original post suggested was your goal — as you are to tell us why your idea is great and perfect. In that case, no need to engage here, just do your thing and be happy or not with it.)
