Not at all, if you can be bothered - just cut insole-shaped pieces of
fairly thick steel sheet, drill them for the fittings and glue them in.
There are a couple of tricky bits:
Getting the mounting slots in the right place - if you ride the bike
with the shoes you're going to adapt you may find that the pedals
leave indentations in the soles that give a pretty good idea where
to drill.
Dimpling the steel insert so the fixings don't stick through the
insole - when you do this it can distort the surrounding metal so
you end up with a curve where you don't want it.
But for the cost of cheap SPD shoes I wonder if it's worth the effort.
