No, because you cannot SetTopo on NURBS. Wanna sign that petition... ? =}
Besides that, it would be a trivial task.

99% confident it's not possible.

Ciaran,
I’m attempting a similar approach now. I think it will be the most
efficient way actually. I’m working on something now which
generates an array with a dense set of step positions of the curve
and a conversion of 0-1 to equal a relative index on the array.
I’ve tried using Get Geometry Sample and Generate Sample Set but
have been unable to get either to work with the density I’m
looking for. I’m curious though, is it possible to convert curves
to linear curves within ICE?

For an OOTB solution, did you try resampling your curve onto a
very dense linear curve, followed by a chord length
reparameterization of that linear curve. UV to location on the
linear curve should give you a pretty even point distribution...

Rob,
This is definitely the issue I am dealing with.
Thanks!

Hi Joey,
about the normalized U - see this thread from 2011 with a rich
reservoir of explanations, techniques, compounds and even an addon
that installs a compiled ICE node that should hopefully give you
what you are after in a speedier rate of milliseconds

also the gradient along the strand issue.. are you talking about
render time or viewport display?
for use at render - its just a color attribute connected to the
material in the render tree. an array of strand color though so
the attribute particle color will not work but if you are using
build strand from curve it creates an attribute called
'coloralongstrands' which can be selected in the rendertree
for viewport display of gradient. hmm don't think so but if your
strands are segment dense then you could do a display hack using
another pointcloud to make a gradient from your strands positions
like so (attached jpg)
