Perhaps it is unnecessary, but it seemed like an idea worth pursuing. Naturally it is easier in conception than in execution.

Having one continuous piece of spacer vs many small ones won't make an iota of difference. You're wasting your efforts. Also, even alloy steerers have a max safe height. If you need anymore than ~ 50mm, your bike is much too small for you.
