Wouldn't it be possible to take the splitter, and with a little
creative work with an angle grinder, reduce it to something resembling
a riving knife?

*Resembling* a riving knife, certainly.

What benefit do you hope to derive from doing this?

Of course this would depend upon the mounting setup of the particular
saw, but so long as the front part of the splitter mounted securely to
the saw, this should work, right?

Depends on how you define "work". One key difference is that a true riving
knife moves up and down as the blade is raised and lowered, whereas a splitter
does not -- and hence your intended faux-riving knife won't either. In other
words, you'll still have to remove it to cut grooves, dados, or rabbets.

And you'll have no blade guard, unless you buy (or build) an over-arm guard of
some sort.

Seems to me that your plan combines the disadvantages of both setups, with few
(if any) of the advantages of either.
