An important step when splicing in aspiration noise is to *replace* equivalently long portions of the voiced onset of the /b/ sound. For example, copy the first 30 ms of aspiration from /p/ and paste it at the 30ms mark of the vowel after the /b/ burst. Otherwise, you get the /p/ aspiration and then the complete /b/ voiced onset (the rising F1 transition). If this is what you've been doing, then I'm not sure why it wouldn't sound good. Another thing- since you are creating sounds from the original voiced utterance, you=92ll get a pitch contour that is too low for an aspirated sound. The pitch manipulation function in Praat can solve this issue as well.
