SE5a’s came in a multitude of colours, most were what we call PC10, which varied from bright green to almost black! Your question about engine size as against prop size is perfectly logical (you must be an engineer) and would appear to be the sensible way of going about things; all I can suggest as an answer as to why we do it this way is that it’s the way it’s always been done, probably because there never used to be much choice of pitch, only diameter, and it’s the way modellers understand. Not really an answer at all is it?
You didn’t seem keen on starting your own “under construction” thread because of your lack of experience but all I can say is that your last few posts would have made an excellent start to a new thread. I’m sure if you mention it to one of the moderators they could move them to a new thread to keep all your SE5a information / queries in one place. But no pressure!

The ailerons are now covered with rib stitching / tapes applied and are “on hold” until it’s time to add the aileron to aileron wire, which will not be until the model is fully rigged and there’s a fair amount of work to do before then.
The interplane struts are given the same treatment as the undercarriage to get the desired finish. The top strut in the photo below has some damage from test fitting the bracing wire brackets; it would obviously have been better to make the brackets and do all the test fitting before I applied the stain, so why didn’t I do that!!!!! Age is a wonderful thing!
The bracing wire brackets are bent up from thin tin plate; litho plate wouldn’t be strong enough. Getting the correct shape to wrap around the struts working from the flat side view was a challenge but PhotoShop came to my rescue yet again, how did we manage before computers?
The top bracket in position.
This is what caused the damage to the strut, any damage will be repaired and the brackets painted before being glued permanently in place.
