...the main reason I am contemplating the blind install again is that it would allow me to re-use the top holes and would simply mean re-drilling the lower holes about 1 1/2" higher than they are now.
If you drill new "blind holes", you will not be able to repower with a new motor in the future without drilling yet another set of holes.
If you drill new lower holes on the BIA standard lateral spacing, you can mount your current motor higher now, reuse you existing upper holes and be able to bolt any other motor on the boat in the future.
Same amount of effort, many more options.

You want to drill the green holes.
