 At hat point can I send the samples (for example from a file with

No.  They will be treated like a 2Msps stream which is what you
interpolated your 270.8333Ksps stream to.  You will have interpolated
your original signal by exactly 96/13 which will give you a 2Msps
stream.

I think you and Brian are experiencing notational confusion with Ks/s. If you treat the post-processed signal as a 2 Msamples/sec signal then the output signal will be a 270.733 Ksyms/sec. I believe that the USRP settings you describe will do just that.
