Yes, it is possible.In vs 6, the words, "If they shall fall away...", would be read literally in the Greek as, "and have fallen away"Hebrews 6:4-6 For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost, 5 And have tasted the good word of God, and the powers of the world to come, 6 If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame. In vs 29, the Greek word translated, "trodden under foot", is a very strong term and conveys the sense of out rage involved in forsaking Christ and returning to Judaism. Or, possibly in this day and age, to what is referred toas judeo-Christianity.Hebrews 10:29 Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite [insult] unto the Spirit of grace?
