Very difficult. There are modules you can buy that convert resolver signals to
quadrature pulses. Otherwise, you can replace the resolvers with shaft encoders.
If your resolvers are shaft type, then I don't think you'd lose any resolution.
I have 1000 cycle/rev encoders on 5 TPI leadscrews, with quadrature
counters reading all transitions, I get 4000 counts/rev, x 5 revs/inch, to give
20000 counts/inch, or .00005" per count.

If you have linear resolvers, then those would be nice to hook to interpolator/
converters.
