b) take a cutter and grind it yourself to the shape you want, using
angle grinder and frequent cold dips? Should manage 2m no problem.

Thinking along those lines I am sure I have seen a recent router cutter
handbook (may have been the trend one) where they had a DIY cutter. It
was basically a core of the bit with a clamping mechanism, and then a
set of flat blades that you machine to profile before mounting in the
arbour/cutter
