No no, actually the first s is /s/ i.e. voiceless as in "sea" or "pass", so the complete transcription should be /kʀiːksʃpiːl/. The transition between the /s/ and /ʃ/ is then just making your lips round for the /ʃ/ after the wide and flat /s/. It is still not as easy as just leaving it out, but it is whole lot more doable.
