First of all, I admit I am being judgemental here. I am sure I might have done so many things that you don't approve of. So my apologies. Understand my frustration as I have been the victim of resume padding directly when I was in the industry; I hated this practice.

Now, you said, " I beleive if u can do that there is nothing wrong with it." I don't think there's anything wrong in joining a company full time while working as a consultant-there might be some legal restrictions from consulting firm but that's legal matter and your firm might not have that restriction. Are you suggesting there's nothing wrong with padding your resume? Almost everybody makes their resume look better by slightly padding it up; the issue is that people blatantly lie about years of experience while they have none. Is this the biggest crime? No it's not. If you know your stuff and you can demonstrate the same ability then it might be immoral but not a crime. But don't say there's nothing wrong with it.

Your life, however you want to live it. Good luck with your background check, most of the time they aren't that detailed.
