I'm not entirely sure what you meant by interpolating or resampling,
but in case you were talking about what I think you were talking
about, that's not going to work. Sure, you can come in at 25 Msps and
resample to 32 Msps, but you won't be getting any more information out
of the signal by doing that. You'll still only have the information in
the original 25 MHz bandwidth, just now sampled at a higher rate
(which doesn't make any difference or, frankly, any sense).
